It depends. I know some guys that wanted to get the biggest baddest amp they could find. They both got Marshall Mode Four half stacks... with 300w soid state power. They don't ever turn them up past 2. It's nice to have a powerful amp, but in this case... they could have gotten a nice combo for half the price and half the wattage and had an extra thousand dollars. It also depends on what options you're looking for. Line 6 has a line of good solid state amps with effects and amp models such as the Flextone III and VettaII combos. Marshall is a bit over priced with it's combos... but an AVT may do the trick for you. I've never really played on a Randall, and I'm a tube guy all the way... so our tastes differ. I think 100-150 watts is sufficient for anyone that isn't playing big gigs. A common misconception though when comparing soild state to tube amps... 2 solid state amp watts equal 1 tube amp watt... So a 100 watt tube amp is roughly as loud as a 200 watt solid state amp. Just something to keep in mind.
