No, not what you think...

... Or is it?
Anyway, I'm in the market for a "reasonably priced" amp. After eliminating anything I really don't want, and anything I can't afford, I'm down to two choices - a Hiwatt Maxiwatt B300, or a Kustom KB200.
I can get the KB200 for (up to) $60 cheaper than the B300 (on eBay), so is the extra justified? Is the B300 significantly louder than the KB200? I'm not overly concerned about tone, etc - as long as it doesn't sound like a f***ing Behringer (my present amp - fortunately borrowed from my brother) - I just need it to be loud enough to do gigs in small-ish venues and reliable.
I can't try them out, as I haven't seen either in any music shops local to me.
