Does anyone know where I can get my hands on one of these?

I've only found one site which sells them: http://www.katanaguitars.com/ but it says that the website only sells clones (I'm not entirely sure)

Also does anyone know if these would be sold in guitar shops in the UK, as i really want to try one out and am wary of buying one without trying it out and regretting it.

Cheers

No, but I can tell you they're friggin amazing instruments. The sound is very airy, but I'm sure you have youtube capabilities. Mine was a lot lighter than my current telecaster.
Fender American Standard Telecaster
Martin DC-16RE Premium

Fender Snakeskin Champ 12
