I recently picked up two sets of older Boston Acoustics A-150's for $225 from a local seller off of CL. It was a total steal! They have both been recently re-foamed and one set is clearly more broken in than the other as bass response is clearly more visceral in the broken in set.
These are fantastic speakers and I'm super happy with them. They are on the short side but they play well above their height and image fantastically. I actually think I may like them better than my Mini's They have great bass with quick and accurate beats and the vocals are very accurate. With the Mini's the bass is there and loud but it isn't as defined and impactful as it is with these old Bostons. They are forgiving, but not overly so, on poorly recorded music. The Mini's are probably more forgiving and are definitely more laid back than the Bostons. I'll post more later but this is the down and dirty on them. Here are pics of the two sets:
