Bizrate.com has decent reviews and competitive pricing all over the net.Just make sure and buy from a reputable seller and watch out for the lowest price quotes,many times it's just an accesory for said camera.
Amazon also has consumer reviews but not as many.For my money I just bought the Minolta S414 from Amazon a few months ago.I got the camera ,a case,rechargeable batteries,charger and a 256 meg compact flash card for like $330 shipped.EXCELLENT DEAL/EXCELLENT CAMERA...Sorry but I don't think you'll find this one again any time soon...LOL
IMHO the two best Digi-cams out there in the $300 price range are the Minolta S414 and the Canon Powershot A70.Amazon has a deal on right now like the one I got for certain cameras with free memory cards or a discount on a higher meg card.The Minolta has 4 megapixels and 4X optical zoom and also takes 30 second videos with sound,you can also add short sound bites to your pics.The A70 is 3.2 MP with 3X optical zoom but you can take unlimited time videos with sound and add sound clips to your pics.My buddy has the A70 and he loves it.I agree though you will probably need to upgrade to at least a 128 meg card and pick up a charger and NiMi rechargeable batteris.Digital zoom is really almost useless and over 3 megs isn't really needed for most applications.
Have fun,JJ :0)
