I have no idea as to whether this is legit or not but for this price ($600 for BOTH a very respectable 500 watt Crown Power amp AND an F1-X) people might want to investigate.  The guy is located in St. Albans Vermont and I'd suspect there really isn't much of an Alembic crowd among folks living in a town of approximately 5,000 people on the shores of Lake Champlain in Northern Vermont.

To be honest, there really isn't much of a market for anything up there.... There's been a lot of PA cabs I've considered grabbing, but the 6 hr round trip might prove rough on my pickup, plus coordinating the trip around my work sched and weather is always a pain, but the deals are there for sure!...
