Routers are platform agnostic. That is, they don't care what kind of computer they are working with. However, that doesn't mean that all routers are on equal footing, especially when it comes to the Macintosh.
Any router you purchase will be a tradeoff between being easy to setup and configure, being well supported (especially with regard to the Macintosh), and price. There are four very popular brands. Apple, Netgear, D-Link and Linksys.
Apple routers are the easiest to setup and use with your Macintosh, have excellent support, and tend to be the most expensive.
Netgear routers are fairly easy to setup and configure, and can be found dirt cheap, but they have been known to have terrible support (this can really vary, though).
D-Link's are mildly difficult to setup and configure, have decent support, and middling prices. (Full disclosure: I recently purchased a D-Link, which replaced a Netgear. After my last interaction with Netgear's tech support, I threw my D-Link in the trash and vowed never to purchase one of their products again.)
Linksys has excellent routers that tend to be expensive and which for many Mac users are almost impossible to figure out how to setup and for which there is little or no Mac support. (Note that the Macintosh isn't even mentioned as a supported platform on many Linksys boxes.)
(These are all gross generalizations, with exceptions, of course. But you can use them as a rough guide. How technically minded *you* are will color your perception of all of these brands. Please let us know what brand you go for and what your experience with it is like.)
You have to choose where you are willing to make the tradeoffs.
A sidenote: Fry's brick and mortar stores often have fantastic deals on Netgear routers that are refurbished but like new. Often they are in a semi-plain brown box over in a corner. I don't see any refurbished Netgear products on Fry's Web site. Refurbished Netgear stuff can only be found now and then on Amazon.
