Any Experience with BCS Gadgets?

Does anyone have any experience buying high end gear from this company, which appears to be located in Pennsylvania? I posted a wanted-to-buy ad on another site for a specific amplifier and received a response from a fellow representing this company along with a link to their website. Sure enough, there are quite a few high end items there for sale, along with other electronics, appliances, and so forth. But still, the whole thing feels a bit borderline to me.

If anyone has any experience with BCS Gadgets, please advise. Thanks!
