Yeh that's a 900MHz Digital line; not too shabby :P... I have a lot of good results with the Digital products that Uniden pumps out, they're very nice :)...
I shopped and shopped for a good phone, couldn't find anything then I came across the
TRU9460 (5.8GHz Digital) phones, couldn't be happier :P...
They have a model which has an answering machine and another which is multi-line compatible that both use the same handsets; so if I needed to upgrade later i can use the same handsets I've been using over the years...
Oh and replacement batteries, on amazon, cost about $2; so it's no bother should one need replaced :)
