Some weeks ago a Sadowsky UV70 appeared in the For Sale section. It was just what I was looking however the seller, jack_b was in Poland, which meant there was no way I could go and look before buying. I contacted Jack and he answered all my questions about the bass. We agreed the price and then to my surprise Jack offered, as I was a long established Forum member, to ship it to me saying I could pay him after it had arrived. Everything went according to plan. The UV70 is exactly as described and it arrived promptly with no damage.
I certainly have no reservations about dealing with Jack again.
