What are some good, but cheap, pickups? I'm looking for ones that can play anything, and ones that can play metal. Right now I'm running some ibanez pickups that were "Designed" by emg....They're still the crappy ibanez ones. (basically they need to play rock, metal, blues, and some softer stuff.)

EMG's are way too expensive for me, so anything but those are good.

People I would like to sound like:
Metal:
Killswitch Engage!!!!! (Closest I can get without Emg's...Although there sound comes from there Mesa Boogies)
Metallica
Pantera
MachineHead
lots of other stuff...
Other(if possible with new pickups):
Ratm
nirvana
Red hot Chili Peppers
Bullet for my valentine
Jimi Hendrix
Lots of other stuff...

The Fake "EMG's" on my guitar are passive...

Here's my guitar btw, in the white finish.
