As I said before you aren't going to find one. There aren't any stocks
anywhere still left. We are the last place to have any stock of any USB
adapter with this chipset. I saw it coming a year or two (maybe more) ago.
Unfortunately I didn't react quickly enough or we would have a cheaper
adapter with this chipset still available.
There is $30 USD off with the coupon code: 30OFFANT. You have to get the
antenna with it though. This coupon is only available because we don't have
the cheaper adapter still and are trying to make this semi-affordable.
Unfortunately it's eating away at the profits. It's an adapter that would
otherwise retail at over $100 USD.

Again I would not advise this chipset except for those setting up access
points anyway...
