I have done my share of experimenting with behringer stuff and to be honest I was not pleased with their cabs.
The 4500H head wasn't completely terrible In the sense that I had it for five years, beat the crap out of it and never had a problem. But, I could never get a good tone from it. It just sounded muddy and clanky no matter how I dialed it in. It also had a really annoying hum that was there the day it came out of the box. I was using it with a behringer 8x10. I replaced the 810 with a GK 410 and it sounded somewhat better, but still not great.
It seems that if you are lucky enough to find a behringer head that doesnt die on you out if the blue then it is decent as a practice/last resort gig head For 250 I think you can probably find something used that you will be happier with.
FYI I lived in constant fear that the behringer 810 had a blown speaker, even though it didn't. Every time I would turn up to even close to halfway, the speakers would fart out like crazy. Even though the head was supposed to be pretty weak for that cab, the cab seemed to struggle. I imagine the 2x10 might struggle even more especially if you use it by itself and you intend to play at anything other than bedroom practice level.
This is of course just my experience. I hope you have better luck than me. I have heard other people say they were pleasantly surprised with their behringer gear.
