Query: Not compatible with the TRU8866 base station

I contacted Uniden for a compatible handset for my TRU8866 base station, and was told the TCX905 is the new handset. Well, it won't seat in the base station to register, nor will it seat in the TCX860 handset chargers. Yet, the TCX860 handset will seat properly in the TCX905 charger.I've contacted Uniden for an explanation that I am sure I won't like.The TRU8866 has been an excellent system. When I had to get replacement batteries for the TCX860s, I bought Duracells at K-Mart at a great price, and they have a better charge than the Uniden batteries.I am really disappointed. I'd settle for a refurb TCX860. I have 8 handsets, and wanted to add 2 more. I do not look forward to replacing the base station and buying 9 new handsets. Not good. Any suggestions on brands would be appreciated.
