Another vote for the Oricom digital here....it hs an amazing range and a very clear signal with no interference...I think we have the oricom 500 from memory....it also has a temperature sensor and it will beep to tell you if baby's room gets too hot or too cold (you set the temp range you want and if goes outside that range it lets you know). The top model also has a video function but we didn't feel the need for that!
