I am using the Ameerican Autowire Hwy 22 kit. I got if for a bit less on Ebay. I like it because the wires aren't preattached to the fuse box, so you can easily add as you go, and like Don said it comes with a lot of extras that make piecing it together much easier. I also like the way they wire systems in individual bags of parts and instructions. I have to admit is is a bit over kill for me, and they smaller hwy kit would have been fine, but it is a nice setup!
