If you're bedroom noodling, don't bother. Learn to make use of the ones you've got and get a decent amp instead.
A good amp can make a crap guitar sound good.
A crap amp just makes everything sound bad.
I have four different amps which hardly get used now. I play through an amp-sim (Amplitube) on my computer almost exclusively at home. It does everything I want or need and very well, too.
