Preferrably Linksys brand. Do NOT want D-Link. They've been less than helpful.

Optimal price range is between $40(wishful thinking) to $65.

Prefferably a B&M store that's local to South Florida.

I think that's all the points. Thanks! :)

Here are some options:

Microsoft MN-730 Wireless 802.11g PCI Adapter - $35.49 shipped

Linksys WMP11 Wireless-B PCI Card - $53.06 shipped (sale ends today)

As for local FL stores, I have no idea. Best Buy carries the Microsoft card above for $39 and the Linksys for $69. Circuit City also has the Linksys for the same price.

Maybe someone else in that area can suggest some other alternatives.
