what do u actualyl need? dont buy what u dont need. lately alot of people have been raving about the Sigma APO DG macro 70-300mm lens as being a superb budget lens. but does it mean u have to get it because everyone says its good? do u need 70-300mm?
here's hwat i suggest. don't get the D50, or the 350D.
get the KM 5D for around $1260. contact: The Oracle. he has sets for sale.
use the Kit lens 18-70mm. take advantage of the anti shake. buy a nice flash 5600HS. buy a lowepro toploader, UV filter, 2nd hand CPL, and a slik 330DX pro tripod. all this will cost you already around $2000. shoot with this first. don't look donw on any kit lens. they are definitely decent and usable.
if you want to upgrade to a constant f/2.8 ;lens later on, get the sigma 24-60 or tamron 28-75.
