The alpha 200 is basically the same as the alpha 100 which was well ahead of the entry level cannon at the time. The main changes are the display and the ISO can go a bit higher.
There are plenty of lenses around for the Sony especially it you check on eBay, admittedly the lenses for the canon are generally slightly cheaper. But the base lens that you get with it is upto 70mm the canon is only 55mm. so you don't need to buy a new lens as soon as you get this camera. What was failed to mention is that the Sony has anti shake built into the body so you can use it with any lens, whereas the canons are built into the lens. so cheaper lenses don't have antishake.
