supe it up? you mean add pickups and stuff? if you really like the guitar, then go for it, but if it doesnt mean anything to you, then wait for your excalibur, so to speak.
I chose the get a better guitar route, if you keep playing it, they tend to fall apart and crap out on you

if you wanted to spend the least money, I would just put in some new pickups (they can make a world of difference)
depends on the model

and if you can afford it, a new guitar would be better imo

get a cheap marshall... my MG15DFX has a button that simulates the sound of one of the expensive tube marshall amps.
