[NTLK] Locating the right WiFi card

[Joseph]

Needless to say, as a newbie MessagePad 2000 user, I've been reading up on everything I can about the device.  I've seen many suggestions that I should simply move to using WiFi as soon as possible and ignore the interconnect port altogether.  I'm ready to do so, but I need the card, of course.  
I've seen several sources, but (once again, I'm new here) I'm not certain who is reputable and who is not.  I don't want to offend anyone here who sells the right cards for a Newton, so I'll just ask:  Where should I go to get a good item?
Also, which driver is the best one to use?  I've seen a couple, but I wasn't sure which was the most stable as of right now.
