Where to buy a Goki (or other) starter for 350x?

[Biff]

I have only found a couple of places that sell the Goki add on starter kit for the 350x. Where have any of you seen this kit for sale? Are there other manufacturers that produce starter kits to add electric start to ATV/ATC engines that don't have them.

Also, have any of you installed one or have you heard positive or negitive comments about them?

Thanks in advance,
Biff
