I bought the Nikon D50 from Buydig a few weeks ago, I bought the body only (for about $560) since my wife tami already has tons of great lenses (she has the Nikon D70). I upgraded from a Canon G5 and a Canon S2 IS (I figured it was better to carry around a superior camera and multiple superior lenses than to carry around two great cameras with great lenses).
I love my D50!
Edit: Oh yeah, I use my 50 f/1.8 90% of the time as well. I carry my camera with me to work every day, and I leave that lens on it. I only bring/use others lenses when I am specifically planning in advance to go photograph something. The 50 f/1.8 works especially well for me because I take a lot of low-light photos (underground in the subway) and I can jack the ISO up to 1600, set a shutter speed of 1/200, and get a decent photo of a moving subway train (or I can use a lower ISO and a slower shutter speed an get a great, non-blurry photo of a still subway train).
