I got one at a local Mexican supermarket for under $5. Works great. I put it in the dishwasher - I don't think it was ruined. This device separates out most of the seeds, and what is left can be filtered out by pouring the juice slowly to another cup.

Pepe's (for both filling and crust) is one of the best recipes. http://www.pepescafe.net/klp.htm

I've tasted/made a bunch (15?) of key lime pies in the last month, and my recommendation is to use the freshly squeeze juice from key limes. The fresh squeezed juice adds a great limey flavor without the acidity that you get from bottled key lime juice (e.g. Nellie's, Kermit's). I used 1 pound of fresh key limes, squeezed using a metal squeezer that I got from a Mexican grocery store for under $5: yielded about 5/8 key lime juice. The metal squeezer filters out most of the seeds, which is great; the remaining seeds you can easily get out by pouring slowly.
