There are many reputable online sources for used camera gear. Annex B in my Canon database (CELOSbd) provides my "star ratings" for about 70 of them. I have actually bought gear from more than half of the two-stars, and the ratings for the remainder are based (primarily) on the quantity and variability of their Canon stock; however, most of them are also very good for Pentax gear and are in the older Pentax database (see SPLOSdb).
There are also many not-so-good online sources for used camera gear. I don't have personal experience with any of them, which is possibly due to the fact that I read this: www.photo.net/equipment/where-to-buy (esp. see "I want to get screwed") www.photo.net/equipment/caveat_emptor Jim www.jcolwell.ca
