Hey Jim:
Honestly, Greg's site is still up and running, however, at the present time one cannot be safely assured that it is he who is currently at the controls. I sincerely hope that this is indeed the case. I firmly believe that it would be most reasonable or prudent to exercise extreme caution when considering a purchase under the circumstances. I would recommend at the very least until you can at some point in time hopefully chat with Greg himself anyhow.
