wireless pcmcia

I have been doing some research on which pcmcia cards are the best for wireless…

By best of wireless, I mean has the best signal strength, most distance away from WAP, and the protocols supported by the card (WEP, WPA, …).

I found this little bugger…which has a 6db directional antanae built into it:

I have also heard a lot about cisco’s Aironet series…but I would like a card that supports a/b/and g. Does cisco have one other than the 11b? Why does everyone love these aironets?

What brand do you think has the best card?
