Found this on Cloudy Nights and one thing seems sure, Meade seem way ahead of any competition when it comes to RD. They are always bringing out new and innovative products, sure some fall by the wayside, but geez in todays economic USA you have to give them credit for sticking their neck out. I think they are providing a shot in the arm for amateur astronomy.
