Yes, several people have commented about range problems; certainly, 3 feet is too short. I'll take a look at RCA again (although I must admit my RCA data is a mess right now, might take a while). For the GDIs, I've just added several Motorola keysets (which also go under the brand name General Instruments; I should probably note that somewhere); with luck, one of the STB keysets (1, 1a, or 1b) will work for you...
