You can get the K710 from just about any shop that carries BMX parts. It's designed to be a BMX street riding chain.
The K710 is 1/8"
The K810 is 3/32"
The K910 is 3/16" (I think this is an oversized BMX thing)
"SL" means that it's up to 20% lighter. They have slot holes in the plates.

The Kool chain also comes in a half link version and I don't think any of it costs more than $25.00 msrp unless you opt for the gold anodized version and can usually be bought at a nice discount.
For multi geared drives I prefer SRAM as it is a little smoother and quieter in this application.
