This thing has been $49.90 for a while at my OM (wonder if it's the same one

)
Anyhow they work great if you leave the deafult settings (accesspoint with SSID: default/ channel 6/ No WEP. Otherwise it's a bit cumbersome to change the configuration.
A couple of points for the advanced user: this thing basically works in three modes: access point (default), bridge (!!!), and wireless access card (plug into ethernet card on PC or other device you want to join into your wireless network).
The lateset version also supports a fourth mode which is REPEATER (boosts a signal to stretch the useable distance of a wireless link) - the ones in my OM did not have that feature - thus they were an older version. I wonder if OM is trying to offload old stock. Still they are good devices definitely worth $49.90.
