Are you sure that it's really defectiive and you're not just doing something wrong (batteries not fully charged or inserted correctly, etc.)?
Did you mount a lens on it and make sure the Aperture Ring was at the minimum aperture position (highest f/stop number)?
Was it a Nikon Autofocus Lens (not a manual focus lens)?
Are you sure the lens is good? Has a dealer looked at it and told you it was broken, or are you just assuming that based on symptoms you're seeing?
Are you sure you're getting a good connection (i.e., the contacts aren't oxidized a bit on the lens mount). Try remounting the lens to make sure it's locked in place, too. How about the battery contacts in the camera? Sometimes a bit of oxidation can build up and it may not even be visible (but, you had a good enough connection to see an error in the viiewfinder from what I can tell from one post).
The last post I saw about it was this one:

But, you've got multiple sets of batteries to worry about, too (as I pointed out in an earlier thread):

Have you tried all switches, knobs and dials to make sure one isn't sticking a bit or not in the right position? Most models can turn the LCD off, too (just by pressing the display button by it and cycling through it's modes).
What condition did the seller say it was in? Did the listing say that it was guaranteed not to be dead on arrival or anything?
You've got to be careful buying used gear and research the seller carefully.
Unless you happpen to be an expert on repairing cameras and have access to any needed parts, never buy gear "as is". If it's being sold that way, it's probably for good reason (i.e., it probably doesn't work). ;-)
But, that doesn't mean that it's not something very simple being overloooked either (but, it could be a very serious problem).
As for the S2 Pro you're asking about, it has a bad reputation for CCD failures. But, Fuji usually stands behind them (even out of warranty) from the last reports I saw. I'd check with them to make sure in case they've changed their policy.
But, I wouldn't buy one just because you have a CompactFlash card and a set of AA batteries, as those can be used in a variety of cameras. I wouldn't buy a particular camera model just because I had batteries and media that would work in one anyway. Those kinds of things are a small percentage of your investment. ;-)
If you've already invested in lenses, you could also use them on a Nikon DSLR. So, you're not locked into Fuji. The body used in the S1 Pro was an entry level film body anyway. Heck, you could always sell the lenses and go a different brand entirely versus Fuji or Nikon (although either could make a good choice, depending on your needs in a camera).
For example, I've used Nikon 35mm gear for years.. Yet, I've sold most of it and I'm shooting with a Konica Minolta DSLR right now (and I bought most of my lenses used at bargain prices).
If you "buy right", it really isn't very painful to switch brands if you want to.
You do need to be a good buyer though. It can get expensive buying high and selling low. :-)
Why did you buy the Fuji to begin with, and what conditions do you plan on using one in?
If you have limitations with your current camera that you need to get around, try to find a model that is better suited for the conditions you plan to use one in. There is nothing wrong with these older models. But, they're not the fastest cameras around, because they're based on entry level film bodies. If you don't plan on shooting sports, fine. Lots of photographers really like the Fuji colors.
In the case of most DSLR models, your lens selection is probably more important than the body anyway. I've got a far larger investment in my lenses compared to camera bodies.
If you're not a savvy shopper and familiar with how to tell if you're going to get a good deal on equipment then I'd suggest sticking to a reputable vendor that will stand behind their products with a limited warranty if you want to go used (at least one that's long enough to make sure it's going to work to begin with).
My favorite vendor for used gear is
http://www.keh.com
If you like the S1 Pro for some reason, they've got one now in excellent condition for $364 right this minute (and IMO, they have the most conservative ratings in the business).
I wouldn't hesitate to buy bargain rated gear from those guys (and I have on multiple occasions). Keep in mind that this is a 3MP camera though (whiich is fine as long as you're not goiing to be printing too much larger than around 8x10").
