It's not much of a looker, and it struggles in signal strength, but Billion's 7300N ADSL2+ Modem/Router has grunt where it really counts.
Linksys' integrated ADSL2+ modem and Draft-N wireless router gets a lot of things right - including excellent signal propagation - but still doesn't live up to the Draft-N speed hype.
If you've got signal problems with existing wireless gear, then the WRT54GX is an excellent solution, but bear in mind it's not yet standards-based technology.
If you want a simple VoIP box with PSTN pass-through, the Voicebox 3102 is it. It's a pity that it's locked to one VoIP provider, however, making it a slightly expensive option.
