I have used the Orinoco Gold 802.11a/b card (not the 'g' you wish to buy), and was satisfied with it. On a side note, this is the 3rd name change of the company since I bought the card in 2000. (Lucent Technologies, Agere, Proxim)
I'm not much help, but hopefully I can get some wheels turning in other people's brains.
Edit - Well it does seem the Gold card outsted the Netgears by a margin, even if the model numbers were different. Still need some other people's opinions though. Thanks anyways!
