I got mine from Vann's for $499. delivery included. Ordered it on a Fri. and they said it would be delivered on Wed. and it was.
I was worried about the proprietary battery also, but have come to see it's just not a big deal. I go back and forth between the EVF and the LCD and automatically keep extra sets in my camera bag(but I did that with the AA batteries too and these are smaller and alot lighter. In 10 years will this battery still be made? I don't know but I'm sure the camera will be so outdated few people will be using them.
I ordered a c-750 in Jan and sent it back. I wasn't happy at all, so naturally I was leary about getting a fluzie but this camera has made a believer out of me. I love it, it's easy to use and I keep my old c-5050 (purchased Jan. 2004) as a back up.
