Suggestion for ADSL modem?

[PearlJam]

I have a DLink DIR-655 router atm and need to get a new modem. So I am thinking a single port modem is good enough.

Any suggestions on what models to look for to ensure a good quality of service from the modem?

Connecting one broadband router to another aint going to help. This would be better ... http://www.dlink.co.za/DSL-2500U.php

The DSL-2500U would be perfect. I'm using one at my home.

Here are 2 shopping sites that list all the SA sites where you can get the D-Link DSL-2500U from:
