they go for around $250
I have been working on getting a comparable rig to Al's incredible GREEN/MATAMP rig. Al used Model T's during the Shrinebuilder tour, it was cool to hear them as bass amps for a change, they sounded killer.
If you want a cheaper (by about 100) fuzz, try going for the Sanford and Sonny Blue Beard fuzz. I had Sonny custom make one for me, it has my initials scrawled on it. It takes FOREVER for him to get around to it, but it is so worth it. It's very difficult to get a hold of him, but if you can, it's SO worth it
