IMHO you've got at least three choices:

1) Keep an eye out for an old used 1980's chromoly steel 10 speed bicycle off of Craigslist. Make certain that you take someone with you who "knows bikes", when you go for your test ride and pick up.

2) You could get this from bikesdirect.com

The Windsor Wellington ~ $350

3) Go to your nearest Schwinn Dealership and get this one:

The Schwinn Sporterra ~ $410
