I looked at horse trailer world, it does seem like IL, has some pretty high prices and the used trailers seem to have lots of rust. Maybe due to the road salts ? I dunno, I really dislike steel trailers. They are initially cheaper but that is pretty much the ony thing. They rust out, and don't hold their value. Buy once cry once. Think about it, how long are you going to be into horses ? A decent all aluminum trailer will save you the extra money in less gas burned. It will also last and look good for a long long time.
