Good low-cost transport?

[Brian Mertz <bmertz@home.com>]

I'd appreciate any off-list recommendations on a reliable, insured,
enclosed auto transporter with rates somewhat lower than the major
classic-car carriers.  I need to get a small production racecar (Alfa)
from Milwaukee to Southern California in the next few weeks.  Ideally
the carrier could bring a two-wheel open car trailer on the same load.
