even if you can inspect before you buy
don't bother buying it ...
if you have your heart set on buying
this sort of gear
get it from a dealer with a return policy
because if you decide you don't want it
or something is wrong with it, it will be bad blood between
you and your friend, but just biz-ness with a dealer.
besides if its a minolta you would be saving a lot of $$ just buying a minolta
( from a dealer or someone that will let you return it ) ..

good luck grainy
