This has been said time and time again, you don't need a huge amp, a 100W isn't twice as loud as a 50W, you can play gigs with a 15W amp, mic it, run it through the pa, if you don't have a pa ill assume you also have no vocals in which case you'll probably need a bigger amp. Also, peavey isnt an offbrand amp, just the crappy ones (i love my prowler).
