My two cents: try to get something better than Behringer. You'll agree on the long run...(unless you're eg. a guitar player that doubles up asbass player in your studio or sumthing like that)
I'll give the Behringer BX300 amp the thumbs up sign. I'm actually impressed with the little BX300, it's a good sounding little pratice amp. The BX300 is not big enough to gig with, but it's perfect for warming up with in the dressing room.
