I was wondering ifotherexternal flash attachments can work as well with the P850, instead of the P20 which goes for $149.

Probably a dumb question, but Im kinda new to ext flash cameras.

I have heard of those "slave" attachments that apparently fire when the built in flash does. I'm sure thats not what I want, because the hotshoe wouldnt even be needed.

Any tips or recommendations?

If you want TTL flash capability, you'll need the P20 flash unit. Other units will work, but you'll need to manually set the flash parameters.

I went to the local camera shop and tried a few attachments.

Some non-kodak flashes still fired, but as stated the brightness parameters are not set. You either get full flash or none (no exposure compensation).

Looks like Kodak has virtually no aftermarket competition in the accessory market.
You mightget the camera at agood deal, but you'll have to pay top dollar for the exclusive accessories. Kinda like what Sony has done.

get any generic flash (vivitar, sunpak, Metz, etc...) with severalpartial power settings, and several aperture (automode) settings. You have a hotshoe, slave flash is not the best option IMO.

If it doesnt sync with the camera aperture, then it would have to be manually changed for every shot,correct?

How is one able to determine what power setting is suitable, compared to the kodak one which appears to do it on it's own?

Also, anyrecommendations on reputableretailers for these such units?

You can use generic flash in 2 modes: manual, or auto (if the flash offers this mode)

Manual: You set the speed and the aperture. The aperture is calculated from the GN of you flash and the distance from subject. Depending on the power setting (if the flash offers several settings) the GN number used to calculate the aperture will vary.
Then the combination speed+aperture give you the exposure of background scene (not reached by the flash)
Make a search on "flash , GN, calculation, ..." on the net, you will find details.

Auto: this mode is more simple , you set the flash at an aperture setting, set the camera to the same, the flash will cut off at the right moment (or the right "amout of light if you want); again, the combination speed+aperture give you the exposure of background scene (not reached by the flash)

The both case, the speed don't have much influence on the flash exposed subject because the flash burst is very short compared to the shutter opening time.

Oh, check to make sure that your flash have a trigger voltage acceptable for your camera hotshoe:
