I've removed about 20 of these Panasonic DECT base stations, (was part of a wider standarisation project) and before I dispose of them, wondered if they are of use to anyone. Ridiculously expensive to buy if you had to, so someone might grab a bargain..

(Also have a few phones for these units as well, these are of varying condition.)

PM me if interested.
