Keith, with all due respect to Tony and his last response, he used the interesting word "hooked" which correlates to my last repsonse to you in another thread here in the pattern section of RCU.
It should be noted, Brenner is definitely on the cutting edge of design and technology and eventually the sales of his Contra Drive unit will "go thru the roof" and the cost of R&D etc, will be overcome. Then, hopefully the price will come down to a more affordable level and many more of us will be able to afford it. I just hope he continues to sell direct to the consumer because we all what will happen if a retailer gets involved___"It's all about the money"! At this point, I would encourage him to resist the temptation. Regards, Everette
