I need suggestions

[KLS]

I'm doing this for a camp that rents their building out to groups that may want internet access.

I'll get a DSL connection and modem. Then...there is one computer in the office. I want wireless or ethernet to that computer, then wireless and USB 1.1 & 2.0 for visitors. I do not know what computer they will bring, thus the need for wireless & both USB. I'd prefer a larger sized access point, not just a small USB gizmo that is easily forgotten and carried away.

Suggestions? I'm thinking of a wireless router, maybe with an ethernet connection, plus a wireless access point with USB connections.

Is that a good idea?

Brand suggestions?

My criteria...
#1...stability
#2...reliability
#3...cost
#4...speed
