I have the 585v6, the next one up from Chris' they are regarded by all the ADSL geeks to be the best ADSL and ADSL2+ routers available, especially if your on a long line as they are very stable at low SNR.
Most of the major ISP's will sell you a speedtouch of some kind or another, For example, Zen sell mine and the 'Be Box' is a 780.
An added bonus is that you can use this to tweak it too.
Its not for me mate its for the miss's her mum lives next door so they gonna share the connection and cost so ive told her easiest way would be to get a router
