Anyone running lokar or aftermarket throttle and kickdown on TQ carb?

This setup on ebay seems to be the same as a lokar for about 1/2 the price...item #310308153008

Well it does look just like a Lokar system but I wonder if it's made as good? I guess you'll never know until you get it. It's possible it's just as good. Then again maybe not. Their 26 negative's of feedback in the last year would scare me off but it's your money.
