A friend of mine told me he tested telephones and they were looking for volunteers. You don't do much and you get to keep the equipment. I filled out a form from this link:
http://www.aatusertrial.com/survey2/aat_volunteer_form_hitech.htm and 2 weeks later, I have a really cool 4 unit 5.8 GHZ unit to play with. Its alot like my current one only better and with 4 stations.
I would give it a try. The company is vtech and the one I am testing for them is an AT&T and seems really high quality.
Let me know if you end up testing one. I am just curious if anyone else gets in.
Oh yea, I don't get anything if you join. You aren't even linked to me at all.
