Input:
I have one of these at home and two in the offices I work in as a Network Admin.  My biggest concern is network security and these come with important security features. You can filter by MAC address, Choose not to broadcast your SSID, choose to have shared key auth. instead of open and you can also enable 128-bit (or 64, if your client doesn't support 128) WEP (oh, and don't forget to change the config page password).  None of these are totally crack-proof, but when used all together they'll prevent most security problems.
My second biggest concern is cost.  These WAPs are a very cost-effective solution, especially in light of the security features mentioned above.  I haven't had any trouble with any of the three WAPs that I'm using.
