I'll second that!
I paid about CDN$700 for a road-worn pair of Garnet 412 cabs a few years ago, so $350 for a new 4x12 of reasonable quality is worth considering. And $250 for a 100 Watt anything is a good price. For that kind of money, I expect to see a transistor output stage instead of tubes, but at that price, hey, give it a try - if you like the rig, you're good to go, and even if you don't like it, you can recover all (or most of) your money on re-sale.
