If you don't own your own trailer and tow vehicle and have to barrow the equipment and get help from friends your going to spend just about the same amount as having it done. I have done it both ways and the costs are very close to the same. By the time you get a rig set up, pay for fuel, meals on the road and lodging it all adds up. Even if you have good enough friends to loan you the equipment and their time at no cost. And as has been already mentioned you run the risk of something going wrong and something gets damaged or breaks down. So its pretty much a toss up. Transporting bikes long distance is not a cheap deal. Lot cheaper to ride them if you can.
