Best Wireless PCI-E x1 Card?

What's the best wireless network card for a PCI-E x1 slot? I'm running Windows 7 64bit if that helps, and I can't use a card on the other PCI slots do to lack of room (big GPU).

Are you looking for one for the best performance at a high price, or a low priced one?

If you need a low priced one you could try the one I got here, for its price it's amazing. The connection I get is always good, however it does sometimes disconnect which can get annoying if you're playing online games ..

How expensive do they get? I'd rather not have to pay a whole lot.
