As far as digitals go, after buying a 60D, I keep the XSi around in case I'm going somewhere camera un-friendly.
That's also my Rebel X's job on the film side, though I've had my A2E out in a decent rain with no ill effects.
As for the OP, I picked up my QL17 for $25, with decent seals but with a sticky shutter and inop meter. I sent it out for a $138 (with postage)
CLA and I'm pretty happy with it now. If you can pick yours up for fifty, and all it needs is light seals, Woot!
