If you reeeeeally want a 1V, then we need to know your region, in the UK ffordes.com, lcegroup.co.uk are good and carry lots of used stock with a guarantee.
I would, being devils advocate, steer you towards a 3 instead.
The difference in price is quite vast, the difference in camera, not so much.
Plastic shell, but metal chassis, same AF, almost the same speed with the PB-E1 or PB-E2.
The viewfinder blind.
The EOS link software (if you have a windows 98 machine kicking around)
The 100% viewfinder (The 3 is 98 or 97 as I recall)
The 1V is a sensationally great camera. So is the 3, and lots more around, and cheaper, and often cherished by amateurs rather than battered by pros.
Just a thought.
