I've been reluctant to switch to DSLR because of the potential problems
with dirty sensors caused by the ability to remove the lens.

Is this a real problem with DSLRs, or not as bad as it seems. It
appears that Canon recommends use of a hand-held blower for dust
removal, but I wonder whether that actually works. Dust is often
tenacious and bonds itself to surfaces in ways that are resistant to
simple blowing. Maybe the best example is my eyeglasses. Once they
get dusty, only windex will clean them thoroughly.

The Giotto's Rocket Blaster safely removes dust from sensors. It has a
very strong stream of air. More importantly the one-way valve at the
bottom of the rocket only lets air in from the bottom so dust blown away
by the nozzle can not re-enter the nozzle so only clean air comes out.
