I've had very good success with the Linksys WPC11 line of cards.  
these work with the wi(4) driver, and use the Intersyl prism II or III
chipset.  I've used the Version1, 2, 2.5 and 3 cards.
the newer cards are quite good in terms of their range, the older cards
less so.  
I'm using the Linksys WPC11 Version 3 card in my Dell laptop, which is
running NetBSD-1.6.1.
