Sensor cleaning isn't hard to do nor is the equipment necessary particularly expensive compared to the cost of a full frame body.
No, but it's terribly scary to do... I've personally cleaned my 5DMkII three times now (with a sensor swab and solution) and fortunately I don't have to do that too often. Happy to report my 7D is still (visible) dust free
