I've simply got an all-Linksys b wireless network going. Most of my network is wired, but where it isn't, I've got a Linksys product. The reasons aren't good, just that I like the brand, the admin is great, and they all work as advertised. That said, here's what I've got:

BEFW11S4 - not used to make up my network, simply to route the cable modem into the switch that most of my computers are connected to.

WUSB11 - for a computer that isn't close to a wall jack. I like this because it's easy to install and remove, and the chord makes it easy to extend for better reception if there's a problem.

WET11 - I use this bridge for my Tivo.

I probably could have done better for price with other products, but it's easy to pick these up at Best Buy, which has decent prices in comparison to the internet, and the router was on sale for cheaper than I could find online. Anyway, that's my setup.
