Small Office router with QOS

Hi all,

I'm after a Small Office router that does QoS.

http://www.solwise.co.uk/adsl-billion-myguard-7202g.htm
looks alright for less than £80, certainly better than the 7500GL (with
Conexant chipset), which doesn't look as configurable.

Anyone have any recommendations? I'm after something that allows a
little more configuration than just "Low, Medium, High" etc. And if it
had backup fallover to POTS, that'd be fantastic.

Thanks for any pointers.
