Cordless LandLine Phones

i need suggestions for buying a cordless phone.

where can i get siemens giga range in Pakistans preferrably in Lahore?

should i prefer siemens over panasonic or vice versa?

There are plenty of them available in market. But AFAIK, their "extra" range is illegal. I have seen them but never used anyone of them.

I do have cordless in my home but it's of legal range (few meters or so). produces

Unfortunately, Siemens is not popular in pakistan :-(
