So far I have been lucky, mostly (I don't count lightseals needing replacement as a big camera fault):
Oly 35 RC bought in perfect condition for 35€, sold for 55.
Canon AE-1 in stunning condition
Canonet 28 in perfect condition!!
Canonet GIII QL17 advertised as very good, wobbly lens and lots of fungus -was refunded by the buyer!
Canonet GIII QL17 in very good condition
Oly 35 SP in very very excellent condition, really!!!
Canolite D flash unit DOA, but refunded
Canolite D in perfect condition
Major problem I had was not on the bay, but from a professional selling cameras..... an Oly 35 SP that was in mediocre condition.
Choose your sellers well on ebay, never buy from 'not camera kinda guy, inherited from grandfather, seems to work, mint condition' sellers.
