I usually stay out of these kinds of discussion here on Pinside, although I do pay close attention to them. The fact that others share their situations is greatly appreciated.
It's unfortunate when people in this hobby/business feel justified in the negative treatment that has been shared here. Suffice it to say, I'll never buy from him and will definitely share that opinion every chance I get. There are enough honorable sellers here to not have to put up with his crap.
