Thanks for the replies. I decided to go with a ZyXEL AG-225h. This is a USB adapter with a built in hot spot finder, and is only ~$10 more than the Mac USB adapter. They have Mac drivers for 10.3 and 10.4 with a Preference Pane for setting up and connecting. It work great on my iMac and I will be in El Paso to set it up on my Sis-in-law's iBook this weekend. Pat
