For those who really can't take a mechanical wheel and believe it will suck the solar system into the black hole, just don't buy it. If you are however willing to take a risk, then report back your finding when you actually have a chance to use it properly. If you are not willing to gamble, then let other do it for you and wait patiently for them to report back. The design has been finalized, whether any of us likes it or not will not change it. You just need to decide whether it is worth your money or not based on what you have seen so far. Keep complaining about thing you have not used or experienced first hand certainly doesn't add any useful information to the discussion.
Lets move on.
