Bugera/Behringer has a very checkered reputation. I will leave it at that.
... largely fuelled and perpetuated by people without direct personal experience. I will leave it at that.
Hey, I'm not going to pretend they're the best quality, because there are better... But my first gigging amp was a 300W head that actually sounded pretty good and never missed a beat when I sold it on (and I bought it used). I have a 45W little practice amp that has been in action since 2007 and has been taken everywhere... still in great condition. I'm also one of those guys who look after their equipment so that might help
I have seen many Behringer amplifiers in local session/small bars as part of their equipment that everybody uses, and I have no complaints...
Bugera is one notch higher in quality than Behringer, even if it belongs to the same company... I keep hearing positive reports from owners too.
Only amps to have actually let me down? Ampeg (twice) and TC Electronic (once).
Bottom line: if you like the sound of the Bugera or Behringer, and you're looking into that budget segment... do it. There are warranties for a reason, and chances are you'll never need to use it. While it's not the best quality equipment ever, it's nowhere as bad as people on this forum want you to believe (they all have stories of someone else who saw or did something, of course
)
Personally, I prefer other amplifiers... but whenever I have to use what's provided, and I see one of the Behringer combos, or a Laney Richter Kickback, or a Fender Rumble... if it's not been abused I'm happy enough, because I know they'll do the job. Because that's another thing, a lot of them are severely abused... maybe because being cheap means they're bought mainly by people who don't know much and they think 100W is enough, and when it isn't they boost lows all the way and turn volume and gain up... an then they fail and it's because Behringer is bad...
