I would suggest you take care to consider some of the issues emerging for many 
Canon 20D users regarding dust on the sensor: there is some growing evidence to 
suggest that this might be a distinctive problem for some cameras.  There are a 
few experts out there who believe more work needs to be done by Canon, for 
example, in either the design and/or prospects for sensor protection and 
cleaning.  Canon's warranty for example is voided if you lose your mind with 
dust-spot frustration and take the risky option of directly swabbing the sensor 
to remove the apparently very stubborn dust particles that seem to have stuck 
on the sensor.  Canon's manual recommends only cleaning with a blower, for 
instance, but if you know blowers, you'll be aware they are not usually very 
successful when you can't get a good side angle to lift sticky dust particles.  
Canon offer a free sensor clean service, but you have to live near a Canon 
service centre for this to be of any great practical use, else you send your 
beloved camera away - three weeks, six weeks, all depends on canon's capacities 
here, so you would be well advised to take these matters into consideration.  
Some bloggers I've encounted make the joke that their cameras came with "free" 
dust: very cute.
