Which USB wifi adapter?

[Sgt_Strider]

None of the computers at home have any spare PCI slots so that is out of the question. I'm currently stuck trying to figure out which USB wifi adapter to get. Which one is better? Does anyone here know which chipset these adapters uses? The adapter has to support WPA security, but I would prefer if it supports WPA2 with AES support. I do plan on using this in VPN some day if the Linksys WRT54GL supports it.

because I had this one:

(not the extreme version though)

and found that the DLink one constantly dropped connections.

I have had no problems with the Linksys one, and from the previous posts on this board, the one that I have comes highly recommended as well.
