Got one
...for a 15" MBP, and I'll agree on all counts. It is expensive for an injection moulded piece of plastic; but it does work very well, I find it to be quite stable (although you could glue or screw it to your desk if youwanted). Also it doesn't seem affect the running temperature or make the fan run more often or louder.
It also docks and undocks very easily, which is handy because at the moment I have to take it out of the dock a few times a day to do a hard reset when Lion crashes :(
I would only ask for 2 things more; a short magsafe cable like the other ones so you only need 1 PSU, and with the power/chargin LED visible from the outside of the dock. The 2nd is a power button; but that is unfortunately in the hands of Apple who don't want an external one.
