@somebrains will treat you right. The Mesa Buster! 200 1x15 combo I bought from him was everything he said it was, and his reasonable asking price meant we could skip the dance of negotiating and just jam out on all his instruments for an afternoon. Seriously, the sale felt like an afterthought; I mostly think of the sale as hanging out and, well, talking bass. We've kept in touch since the sale and he's been very helpful in getting to know my new-to-me rig. Buy with confidence, but not his Spector; that too shall be mine someday, bwahaha! (Seriously, though, you could buy that Spector and you'd be fine.)
