I soooo loving my new Canon T3 I got a few weeks ago, with the kit lens (EF18-55mm f/3.5-5.6 II). I see my photography progress every time I shoot with it! Recently I had to get a nifty Canon 50mm f/1.8...sometimes you just need a faster lens. Added a bunch of nice quality filters, as of late, to round things out.
I really wanted a Canon 7D at the time I bought it (a birthday gift to me, well, really a 5D Mk II) and I actually picked-up a 7D a couple of days ago and could not believe how heavy it was! I better start lifting weights :) Now that the 5D Mk III is out, that would be a step-up but I think I'll keep my sights on the Canon 7D.
