Car Haul Trailer, Steel vs Aluminum, Which Would You Choose?

I have had both, just sold a Aluma trailer full deck 18' all aluminum trailer. It comes down to two things how much you want spend and how much you are going to use it. If you are going to use it a lot and tow all over the place , then go with aluminum. if you are going to use once in while go steel.
Steel trailer-these are best bang for you money-http://www.econotrailer.com/
This is the Aluminum trailer I had -http://www.tptrailersinc.com/store/OPEN-CAR-TRAILER--UTILITY-TRAILER--ALUMA-w-FULL-DECK-6-6-X-18--GVW-7000-OSCARItem_4=78033.aspx

X10 I can buy a steel trailer here, that you will have to put rims and tires on for $2k, but it comes with junkyard tires and wheels to pull it home.
A sweet aluminum one is 5K, tricked out with aluminum wheels etc.

The aluminum car trailer weighs 1k lbs, the same as my 6 x 12 steel utility trailer.
Steel ones are about 40% more heavy.

My next trailer will be aluminum, because I only have a 1/2 ton truck to pull with.
