I purchased a Nikon D70s from beachcamera.com and everything arrived as expected and in perfect condition.
I know someone told Zach to check out http://www.resellerratings.com/ in an old thread about searching for his D200. This site provided me with a wealth of information concerning online stores. Check it out if you haven’t already.
I’ve been seriously photographing for ten years, done most of my business for equipment and supplies online, and I’d second Eric’s comments about sticking with B&H, Adorama, and Amazon.com as your sources.
Like Mr. Patten stated previously, Beach Camera has served me well. I bought my D70s and some odds and ends from them last year with no problems. I’ve also had good luck with Amazon.com. Best of all….no followup telephone calls asking me to purchase accessories from them.
B&H (usually my first choice for main equipment)
KEH (used equipment)
Amazon – (I use them for related gear and assessories)
Porters Camera – Perhaps overlooked because prices tend to be high, but they are in the midwest, service is good, and they carry some specialty or different stuff sometimes. Check them for assessories.
