If you like it, and have the money for it, why not. Looks like a cool piece, but I would think that price would be at the top of the scale for what it's worth. Being out of the biz for a bit, I could be way off, but $400 sounds at the high end of fair. I got my great condition JC-120 for less than that a couple of years ago, and I've seen JC 77 and 90 amps on Ebay for quite a bit less. Vox makes some great amps in the under $400 range. I just got an AC4TV for $259 that is really a fun, cool little tone monster.
The Gibson does look cool though
