NAVL is obviously a good recommendation, but have you heard of UShip.com? It's sort of like a reverse eBay, but for shipping only.
Basically what you do is set up an account (free) and post an 'auction' stating you need a Ms. Pac-Man shipped from Orlando Florida to Omaha Nebraska. You take some pictures of your cab, post some decent measurements and weight, and then companies bid for your business. You'll be hit by big companies at first, so you'll get offers for $700, etc. But then you'll get small trucking companies bidding. I was able to ship a Sega Megalo410 from Austin TX to Atlanta GA for a little over $210.
There is even feedback on the shippers, posted by the sellers. So, sure you have to worry about the guy that's got -50 feedback, but that goes with any type of auction house.
The only other draw back is that lets say you get an incredible price like $50 to ship it with insurance, wrapping, pickup at your place, signatures, etc, all that good stuff. Sometimes, even with that, the shipping TIME will vary - of course this varies by trucking company. Some shippers will respond and say that they can pick it up on a certain date, and then have it delivered in 3 weeks, or whatever.
Those are worst case scenarios, of course but I had a good experience with UShip, so I figured I'd toss that into the mix.
