Ebay - here. I have occasionally seen them pop up at other stores too.
Have you thought of trying Pure Tone pickups? I had one of their 'buckers and it sounded pretty good for it's price - much better than most other stock generic pickups I've heard.

yeah i looked at puretone but from what i have heard their single colis arent as good as gfs, i could be wrong.
