I've been looking for a solid amp head for a long time now, I'm still undecided between a combo or head, as I have a 2x12.

I'm looking for something in the $500-750 range.

I've tried the:
Bugera 6262
Bugera 33XL
Peavey ValveKing 212
Kustom Defender
and a lot more..

I'm looking for something can achieve of a Motorhead crunch, or around there. I was impressed with the 6262, but I'm worried about the reliability because I'll be touring a lot this winter, and the last thing I need is a break-down on the road with no money or home to stay at.
Player, give me some brew an I might just chill
but I'm the type that like to light another joint like Cypress Hill
