Got myself an IBM Model M a few months ago. It's a unicomp version so not a classic. Got it for about 40 bucks. I love the buckling springs. Poor quality photo but great keyboard.

I'm looking to make some modifications to the KB. First I wanna add some EL wire under the keycaps to illuminate it. I really wanted to make it backlit( but don't think that'll happen). But from a quick google perusal, the EL wire illuminating looks great on some kbs but others looks crappy. Any tips on pulling it off?
I also want to change up the colors on the keycaps. Where can i get keycaps for the model M. Another option is for me to dye it. But i'm looking for new caps and haven't found much luck.
