I am getting mew DSL service from Qwest, and am going to use an Actiontec 1520 or 1524 wireless ready modem/router/gateway. It has a PC-card slot for adding a wireless 802.11b card. Anyone have any experience with these? I want to ad the card, but not the Actiontec one for $50. I want to use a cheaper one, like from eBay or overstock store. Thanks.
