I noticed the one you were looking at has a wireless adaptor bundled in with it. You might want to take a look at this......I got this
Belkin B5DUK045 G+ MIMO router and adaptor package from PC World the other week. The price seems as good as anywhere and the adaptor is worth £25 (although you dont need to buy another £25 one if you want to add another on - I bought a cheap £10 one from play.com and its fine). Its a nice bit of kit. Well recommended.
