Overall, I had a good transaction with JonAz. I paid via MO (I shipped first) for some Red E-Vents, and he was very easy to deal with. He kept in contact, was willing to work with me on shipping.
However, when the mask came, there was paint all over it, in every feasible part of the mask. The lens was very scratched up, something he hadn't pointed out, but I tend to be pretty picky about my lenses. It took me about a half hour to clean out the mask, and is definitely not something I would have expected for a "great condition mask." However, all in all this was a good trade, just a few hiccups along the way.
