550D Potential Purchase. Help Required

Go to Target. Every one of their stores just marked the t2i as clearance. Well run stores will have a rarely touched floor model with a lens locked into place via steel bracket, since the day it went up. Poorly run stores will have the body only displayed, with the mirror and sensor exposed, because theyre more concerned with selling Kodak point and shoots. Got off topic, but here's my point: Many Targets sell floor models at up to 30% off the current price, which will likely be in the $550 range. a sub $400 discounted price might be the end result. My friend beat me to the Nikon D5000 last year after it dropped to $200. He's used it faithfully with no ill effect from it being a floor model.
