Wireless gaming adapter?

Alright i have a linksys wireless g gaming adapter. But it doesnt have a good range. I was thinking about buying another one n perferably. BUt it would be hooked up to a g router until i got fios. (its not out in my area yet) So anyone got any ideas? It needs to be around $80 or less. Must get good range for my internet plus my neighbors when mines slow. (i have his permission btw he gave me the password) And it has to be able to hook up to a router to give connection to an xbox 360. Im not buying that microsoft p.o.s. So any suggestion would be appreciated. Was looking at the linksys wga600n but heard it doesnt get very good range.
