Well if you can find a way to get the Acoustic combo go for it, I've had a BA115 for 2 years and I regret spending $350 for it.
I don't know anything about a 200W BA115? Mine is 100W. It works good as a monitor in small/medium gigs.. Don't hope for much more than that.
The amp does have a terrible tweeter hiss, I disconnected mine and I'm much happier with it. (Still don't like the amp, though)
They make quite a few versions of the BA115 now... there's the BA115T (with a tube in the preamp), the BA115HP (high power, forget the exact wattage), and then a high wattage one with a tube. All sorts of options. personally i can't stand the preamp, so i'd go with the b100r or b200r.
