[NCLUG] Modem Source?

[Michael Riversong]

Need to put a modem into a Gateway E-4200 running Fedora Core.  Nobody 
here in Cheyenne is carrying anything with any support or possibility of 
return, which means that buying one could be a huge gamble.

Does anyone know of a source for such a modem in Northern Colorado?

I'd like to avoid ordering something online at this time, due to 
personal circumstances.
