As has been mentioned on thefret.net before, Bugera (pronounced Bujera, not a hard G) is Behringer's high-end line, "hand-crafted" in China (as is the Vox), but supposedly point-to-point hand-wired, etc...
I, too, have read good reviews. One of the two local shops here carries Bugera and Vox, so I've played thru both (own a Vox AC15). The Bugera is a pretty nice amp on its own, BUT, this is a shootout w the Vox AC15, so here's my 2 cents (trying to be as objective in my subjectivity as is possible

):
I used to check out the Tone King's demos alot, but he just got to be too much. His whole reason for being is overly-distorted metal. He wouldn't know a good clean sound if it bit him in the arse. To him, the BEST sound is equivalent to a speaker mounted in a metal garbage can. (But, God Bless him, he does try very hard and seems like a nice guy...) That said, there is no comparison to my ears. The Bugera sounds stale and stiff and mechanical compared to the Vox's organic, more tube-like sound - clean and distorted. I would spend the six bills on the Vox in a heartbeat (oh, I did!). Sure, $350 is a savings, but if the savings buys you a lesser sound, what's the savings worth? You can always spend less on anything, but if that savings isn't buying you what you want, and prefer, then it's stupid to talk of a price difference (within the context of what you can afford, of course).
To sum up: I think the Bugera, stand-alone on a showroom floor, sounds pretty nice. But, compared to the Vox, it is lifeless and I wouldn't buy it. Nothing else sounds like a Vox, baby, and that's the reason Vox is so popular..."the relentless pursuit of tone"! He is comparing apples and oranges here, as far as I'm concerned. Oh, yeah...don't forget the re-sale value, also.
That my story and I'm sticking to it!
