I spent a couple of hours with the Hori Ace-Edge when it came out (bundled with
Ace Combat 6) and I was quite happy with it. It had a solid base, crisp buttons and a responsive stick. The Ace-Edge does not work with a PC, and I'm not sure if it was ever sold separately.
There is also a stick made by Saitek (who are now owned by Mad Catz), though I have not tried it. Unlike the Hori Ace-Edge which has separate throttle and stick units, the Saitek is a single piece. This one apparently works on a PC as well, so it might be a good option for you.
