From what I hear the shutter mechanism on cameras have a certain number of shots before they fail - 10,000 shots or whatever. Do you keep buying Rebels or have you not had a shutter mechanism go?
Shutter assemblies have gotten more durable with each generation of camera.
My first Canon DSLR, a D30 (the 2000-2001 model that was also the first DSLR manufactured by Canon), had the shutter mechanism fail three times. Fortunately, the first two were covered by an extended warranty. The D30's shutter failures were odd; the flash stopped discharging, but the camera would still take pictures. Canon replaced the D30's shutter mechanism with the assembly from the second-generation D60, but it still was fragile under heavy use.
After the D30 went down for the third time, the most affordable Canon DSLR available was the original Digital Rebel, the 300D. Both of the Digital Rebels I bought had shutter failures: one when a shutter blade broke, the other when the spring failed on the unusual hinged shutter cover. Those problems arose even though the 300D was limited to four continuous frames in a burst, which should have limited stress on the shutter mechanism.
Then I moved to a pair of XTi's, which have had no shutter problems. However, the shutter buttons on both cameras needed to be repaired. The XTi's remain in use as bad-weather backups after four years in service.
The current first-string camera is a T2i. It's handled tens of thousands of exposures over the last 11 months with no hints of trouble.
The Digital Rebel series has offered good performance at a relatively low price. With Canon's history of releasing new models with upgraded features, it should be time to buy a replacement for the T2i in 2013-2015.
