Off-Topic?? - Car Trailers

I don't know if this is off-topic, but I figured I'd get the most views in this group. Mods...please feel free to move if necessary.

I am looking into buying/building a car trailer. A buddy want's to go halves with me and share it. He wants to get together and build it. I thought I've heard you can buy one cheaper.

Just wanted to ask what kinds of things I should look for when shopping for one, or for parts for one. I've heard rumors that some don't have enough tie downs points, tube is better than channel, tilt-back vs dove tail. Any info would be greatly appreciated
