Likewise I'd avoid D-Link (or delink as they're referred to amongst my colleagues given the huge number of dropouts experienced on D-Link WLAN kit) and Netgear (awful support function)
Which leaves you with Linksys, Thomson Speedtouch, BT & 3Com of the major consumer brands (if excluding Belkin - I'd say good choice to avoid lol).
I've not used a Linksys myself, but they are now a division of Cisco (like Aston Martin is a division of Ford) so in theory at least they should have the pedigree.
Thomson Speedtouch are long standing DSL providers to the UK - being chosen by BT when they initially rolled out the 512k ADSL to the country. Good solid routers and not too pricy.
BT actually rebrand some decent performing kit in my experience - I hate BT with a passion but the Voyager 2110 I have at present has outperformed my expectations and it's predecessor considerably. Hell they even answered presales questions by return of email.
My 3Com would still be here today if NEDL hadn't shoved a spike down my mains which fried the router - in my experience great support if there's something wrong.
