If you had about $600 to spend on an amp, what would you go for? Just looking towards the future.

What type of music?

I play Death Metal and my line 6 spider III works for now. Which was around $500

once I get more money I'll probably go for mesa boogie or krate

2008 M.I.A. HSS Strat

yuk valvetronix, i have to say mate, unless you plan on gigging etc, 100w is unnecessary, and try to get something all tube
