Go with Marshall. Look around here and VHforums and you will see many folks swapping 5150's for Marshalls. Ask Sucka what he thinks of his Marshall that he swapped his 5150 for...
The 5150 is just too much. Hissing all over, and a guy I know had problems with switching between channels and we always had this highpitched squeal. Real friggin' annoying when you are trying to play a tune and you get that feedback with that gain. You can't go wrong with Marshall.
Check out the AVT series. I have a half stack
50 watt head for around $850 brand new, so I am sure you can find a good deal on them. PM if you want some samples of my live tone, and talk to Sucka. [img]images/smilies/icon_thumb.gif[/img]
