I am curious myself, the reviews I have read have been mixed some loved them some well not so much. The only real negitive I have been able to find was the software would not allow you to reassign the keys, you were stuck with the provided profiles - there are FS9 & FSX profiles included. Personally my thought is they look like a very good buy, I am not too concerened by the profile editing, I would expect it will be customizable via software update - if it has not been already.
I am building a console now and I have left space for a set, it is just a matter of time before I take the plunge, my spending on Flight Sim gagets always goes up in the fall...
