Nice, congratulations on your new bike, WombatCA!

You could do a search for used racks in your area. In Portland, we have a local business whose specialty is used racks, especially Yakima. They have very good prices and great customer service (they make sure all hardware is in good working order and help with installation). Maybe there is a similar business in your area.

Enjoy that new bike, what a great way to start the new year.
