Well, seeing as how I am the guinea pig for this adaptor plate, I think it is a very good piece of workmanship and considering all the relevant factors, fairly cheap. I looked for the Blitz version and all the tiny bits of available info on it and it didn't impress me and wasn't available. The design and manufacture of the one I am getting was brilliant and a combined effort of a couple of people, one of which is selling the end product. We should have results within a week and I will be more than forthcoming with the results. Have a look at the pictures and don't be too quick to judge.
