i want to get a dslr soon. probably a rebel xt .... but for now i'm content with my sd450
i highly recommend the Nikon D50 instead of the xt. i researched which, or whether even i wanted to get a DSLR for a few years. i bought a couple of point and shoot joints and then i bought one of the really old kodak tank-like dslr's.
i have a canon EOS 600, Olympus R35, minolta xg, kodak DSC, a couple of disposable joints, nikon FE and now the Nikon D50.
below is a link to a show i shot last weekend with the D50, manual lens, 800 speed, with a little external flash. http://www.flickr.com/photos/2ndthought/sets/72057594068047878/show/
