You can purchsae Engenius products from several different wholesale locations- Graybar(www.graybar.com), Anixter(www.anixter.com), Inter-tel(www.inter-tel.com), TeleDynamics(www.teledynamics.com). I have personally used Teledynamics. The handset itself (no base station) has an MSRP of $199 (should give you an idea). I have not tested the range of the two way feature, but I have used the entire setup in large houses and have been able to walk around the block and still be well within range of the base station. No other cordless phone has come close to that! Just my $0.02.
