HEHE With access points all you need to worry about really is the quality of the product. People have many different outlooks on different brands due to past expirences or just word of mouth.
My suggestion personally would be to do your own research and find what suits you the best. Linksys is a very big name in networking due to Cisco being part of that deal. Netgear is pretty basic networking and more likely to be affordable no problems with mine yet. D-Link, well, not sure what to say about D-Link other than it's hit or miss.
Do keep in mind though that Wireless signals no matter what the brand can drop out if there is interference such as a wireless phone being operated (phone and router operating at 2.4 or 5.8 Ghz) Also Microwaves, refridgerators, power lines, and believe it or not pine trees.
P.S. The Wii has a built-in Mitsumi DWM-W004 WiFi 802.11b/g wireless module which means b or g is supported so don't worry too much about your router operating off of b or g.
