good fast searching & dialing phone

[bartvisser]

In our company we have a couple of Habimat phones.
They are phones which can store a lot of names and phone numbers. see :

You can realy search numbers verry verry fast dial them.
It is a realy good phone if you have to make a lot of calls.
BUT...

They are also expensive! and we need to replace them soon.
I am looking for a good alternative for it.

And i do not want to use PC/CTI dialing. I just want a sort of phone with good searching options in it.

Thanks
