SOT: looking for good cordless phone sets

[Philip Lewis <flip+@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Our ATT 24?? series phones are giving up the ghost. (some don't ring,
batteries failing, no handsfree on some units... etc)

I'm looking for a set to replace them, and though it isn't
specifically on topic per-sey, I thought folks here might know.

Our current system has 1 base which plugs into the wall, and three
remote phones. (4 cordless phones total.)

Features that i'd like:
*at least 3 cordless phones, 4 would be good.
*only base unit needs to be plugged in to phone line
*Remote units have chargers.
*Multiple cordless phones can be in use at the same time. (unlike a
 vtech set my g-ma has, which only allows 1 cordless to be in use.)
*takes *STANDARD* rechargeable batteries (AA, AAA, 9V, etc)
 (the current ATT wants a special battery which is just 2 AA cells in
 a custom holder... cheapest i've seen is $15... that's crazy)
*5.8 might be nice, so it doesn't compete with microwave and wireless
 network.
*base unit having a battery backup would be nice, but not necessary.
*headset capable might be nice...although we don't use it now.
*handsfree mode on base (minimally) and handsets (would be nice)
 (note: if base is corded... the handsfree is less needed there)

Budget is around $100... though less is always good.

Any recommendations?
