Can i suggest you send/pm that link to G or rod1, who seem to know most of the players in the market. I've not heard of them (not that I know that much) but I have to say the website is very vague, with little or no detail. That doesnt mean its a problem, but i would expect to see an address or location at least. Also check the cfi is listed as a qualified instrutor on the bmaa website
Finally if you browse many of the threads, the general advice is to be very wary of paying up front. Not sure if paypal protects you from this, but it may well be worth paying the few hundred pounds extra so as not to have to pay all up front.
Either way, good luck, you'll love it!
