So I have a dean z-x that is absolutely nearly perfect to me, and all it needs is a whammy bar. It does not have the screw in hole for most, and I don't think it has the right bridge for this... I'm a noob at modding guitars and stuff to try and keep it simple. Any cheap solutions for this?
No cheap solutions for that. A Floyd-Rose (which is the standard in whammy's), is expensive, (probably more than your guitar cost originally), and requires routing of the body.

A guitar luthier could rout the body and install the bridge, but you're talking big bucks there. Might be a better idea just to go find a guitar with a whammy bar already built-in. That's what I did and it weaned me of the "wanky" bar real fast.
