I've seen the full version; pretty nice but I personally don't feel it's worth it for this level.
I subrscibe to TruckersEdge
www.truckersedge.net and post the trucks there. It is powered by DAT and only costs like $19 a month. I don't really like the interface for searching for loads and rather use ITS. The other guy I work with likes Getloaded. I just use TruckersEdge to post.
Out of the three load boards Truckers Edge is by far the easiest to post. When people call I ask where they saw the truck posted and DAT (Truckers Edge) seems to draw a lot of brokers.
Sometimes if I'm having trouble finding a load I do search on Truckers Edge and there are many companies that seem to post there and not on the other ones. But like I said I don't use it for searching too much.
Another reason I like to use Truckers Edge to post is I can put different phone numbers. (like cell phone if I'm out of the office)
TruckLoadRate has a new load searching function that seems to have loads posted that aren't anywhere else. I don't know what it's powered by.
