Doubling the price you say. I sort of admire people doing a service and adding a fee, but doubling it is a bit naughty.
I'd actually rather never have a kit than buy one from him if he's doubling the price.

I've not worked out what jauce actually is.
Is the jauce site a cover of EBay? I looked and can't find an EBay for Japan.

I need to look into this and will follow what you guys do with interest
