UPDATE: I've made my choice. Thanks for the advice!
Now that I have a PC running Windows Vista instead of XP (Vista being the one that doesn't support Nintendo's Wi-Fi dongle), it's time for me to be dragged kicking and screaming into setting up a wireless router in my home. Before I just jump blindly into buying the first piece of hardware that looks good, I thought I'd ask all of you out there for some advice. Can you recommend a solid wireless router that supports Windows Vista and plays nice with the Nintendo Wii, DS, & Sony PlayStation Portable? At the moment I'm eyeing a Linksys WRT54G router based on recommendations from both Nintendo and Sony, but if you know of something better, please speak up.
