Need a new wireless router.

I'm in the market for a new wireless router. I'd like somthing with range around 100 feet (if possible).

Why cant router list max range as a specification?!?! :( It's hard to specify distance between routers because they are all Wireless N and come with antenas.

Anyone have any experience with routers with good range?

Third party firmware will let you change the power to the radio. Google ddwrt
