True, the amps they are currently selling are not on their web site. I have seen a few that were listed there for sale on Ubid, so it depends on how patient you are.
As for the amps Ubid is selling now, they are older factor reconditioned ones, don't be fooled. The one I got works great, sounds great, and only had one minor flaw: an adjustment was mislabeled.
The website listed above is the correct address. They appear to be a small, very focused shop. Try doing a search here for ads, you might find some other things of interest.
