I've used Forward Air numerous times; they are very affordable and the service is good. I have a Cyclone en route now to San Diego from Quebec - total cost, including insurance, was $150. The crate is about 78"x26"x20" and 50 lbs.
The only downside is they do not pick up or deliver - you need to go to a local Forward Air (or partner freight consolidator) depot to drop off and pick up.
Call them at (800) 726-6654 or (614) 497-4622; web site at

I have no connection, just a customer.
