Just my 2 cents here...
Having a fabulous guitar with a $h!++y amp (or no amp at all) is just silly...
Go for an RG (most small shops are practically GIVING AWAY 550s, 560s and 570s that have been hanging on pegs for years...)
Then do as Jono suggested -- get a used 5150.
I can't speak for the combo amp, but I've been using the original head for over five years now.
It's been retubed with Eurotubes (http://www.eurotubes.com
) and has 1,000 times more versatility now than it did with the stock tubes.
In fact, I like the thing so much I recently picked up a 5150-II head. The clean channel on this one is like butter -- the first clean channel Peavey has EVER nailed. The lead channel is pretty much the same, with just a little more bite in the high-end due to an extra 12AX7.
I like to think I have a discerning ear when it comes to guitar tone -- and the 5150 is certainly no beginner toy which you tire of quickly. The Pod on the other hand, was just that.
But don't take my word for it -- go try one out and hear for yerself. After all, I like chocolate ice cream with chocolate sauce over chocolate cake. (with chocolate sprinkles...)
