can i use this in Asia?

Don't see an issue with that

Only difference might be the Caller ID, but RJ-11 should work the same all over.

And power/plug issues

My family has this... great for a big house. Lots of headsets make it easy to get to the phone quickly

any idea what the range is of these?

^ range depends on what else using 1.9GHz in the area, # and angle of walls, etc. Generally it will work in a medium to larger house and 100' away outside with the base in a room with a window. YMMV.

Went and picked one up in-store today...online rebate process is very easy. Used a 10% off coupon to save an extra $12...don't like to have to pay for coupons in the first place, and don't trust the e-junkie process...still a good deal without it, IMO

i bought these, got the coupon, rebate and 1st markdown, cost me about $50 with the tax. i like using regular batteries too. nice

good deal

silly question: hows the 2.4ghz compared to 1.9ghz? lower number the better?

Incredible deal for $45.

5 phones - wow. I can remember when I was a kid and we only had 4 phones.
