Behringers are good? i dunno, they kinda have a bad reputation for quality control, or so i heard. the one i had didn't sound very good either. or maybe it was because it was only 15W.
i'm using a Orange Crush 20B now. sounds pretty good and can get quite loud, my volume never goes past 2. i wouldn't mind trying an Ashdown though...i've heard good things about them.
