I bought several cameras and lenses from him when he was selling on Ebay. Most of the stuff was not in perfect condition, but I felt that, given that I never paid more than $35 with shipping for anything that I bought, I got what I paid for. Here are some examples:
Praktica PLC3 - the light meter did not work because of a broken wire. It turned out to be a simple repair which I could do by removing the bottom plate. Amazingly, the batter was still good (and still is, two years later). I paid less than $30 for this camera with shipping. This is one of my favorite M42 cameras.
Minolta x-300 - It came with an off-brand, junk lens which I expected and the film counter does not fully reset. Other than that, it is a perfectly functioning camera.
Pentacon electric 50mm/f1.8 lens - works perfectly.
Agifold - Agilux - The slow speeds don't work but since I don't normally use anything below 1/30, that was not an issue. The lens and bellows were in good shape.
I have looked at his web site a few times since he stopped selling on Ebay, but I did not see anything that I thought was worth spending my money on.
