You can get a refurbished 30D (I got one a year ago and have had no worries) for $549, and a refurbished 18-55 IS for $119, leaving you a bit of money for the 50/1.8 (around $75) and the other bits you'll need. PM me if you want the store info- I don't know if you can post it in public on here. It's a big and reputable US shop.

Cheers
