I want a shector next.. do you think I could get a somewhat good shector ( or shecter however its spelled) for around $500?
Especially if you get a used Schecter, you could certainly get an upgrade from the Epi for well under $500.
I got this Schecter Tempest Special used for $250, w/original hardshell case:
Although the shape is somewhat non-traditional (Schecter's "Tempest" model shape), the P-90 type "soapbar" pickups would be great for blues or blues-rock. You could also get an Epi Les Paul Special (different than the "Special II" you have) with the same type pickups:
Both the above models are discontinued but you could probably find them used. You mentioned getting a Telecaster, and yes, they're great for blues/blues-rock. A "MIM" (made in mexico) Fender Standard Telecaster would be a good upgrade:
A traditional Tele with 2 single coils in the Squier Classic Vibe Series is another option, here's the "'50's" model:
You could also look around for a Telecaster with a humbucker in the neck, rather than the traditional single coil. Squier makes a Tele with a "neckbucker" in its vintage modified series like this:
and I have a '90's MIM Fender Telecaster with a neck humbucker that's great.
You could even go a little further outside the Tele "box" and get the P-90 "Tele Custom II" by Squier:
Almost any Tele should be good for the more trad type music you mentioned. If you want to be able to do Metallica too, though, get something with at least one humbucker.
