I love it. Plenty loud (with a portaflex 350, I rattle things before reaching 9:00 on the master volume), sounds relatively flat (not scooped). It sits on a carpeted concrete basement floor and any thing over 1/3 volume I can feel the ground vibrate. It is heavy (by TB standards) at 85#, but it has side handles and I can easy shift it myself. best part is that they do seem to sell inexpensively both new and used (at least around here, within 100mi of where they are made). My brother is surprised that I haven't broken one of the mirrors on the wall yet; and so am I. I am still impressed with the bargain I got on it - C$200 - so much so that I have left the price tag on it as a point of pride.
These things are durable. Traynor built them to be able to fall off a stage and keep working. There are videos of them tossing amps off the top of the building to test them.
If it is a good price and in decent shape, I would tell you to buy it.
