Musicman 120B Bass Head... what's it worth?

So I'm getting a Musicman 120B bass head in a trade.
It's the only fully solid state head that Musicman made. It's 100 watts rms.
Anyone here know?

I know that yr looking at a hamilton craigslist for $300. offer $250, good deal. A dude on harmony central says he paid $320 for one and has seen them >800 on ebay.

Haha, I'm the one trying to sell it at $300 (in Hamilton)... I had an offer for $250 that fell through, so I though I'd list it high to leave some bargaining room
