Canon EOS 450D Digital SLR Camera Kit (incl EF-S 18-55mm IS f/3.5-5.6 non USM Lens Kit)
If you've gotten matches from HotUKDeals, you can probably get it a little cheaper. This price just dropped as well. Was £502.99 this morning. Better than the Argos deal I posted this morning as the Argos deal was for the non-IS lense. It's better than Play.com which is priced at £679.99 contrary to what the other guy posted.
