I would not worry about the brand name if it is built good. Look for quality items like dexter axles, good wiring in conduit or grommets where it goes through metal, nice lights, plenty of tie downs and the most important thing in my opinion is that the the steel that makes up the A Frame that goes up to the ball coupler extends all the way back to the first axle area. Many cheaper made trailer will only go back about a foot under the deck and will warp the trailer, make it go sway back, and cause welds to crack under time. Make sure its not under built or over built. Nothing worse than a trailer that weights so much it can not carry any real load. For example my 18' car hauler only weighs 1,300# and leaves 5,700# of weight capacity out of its 7,000# GVWR. I see ones all the time that are 2,200#+ and that is a killer for 7K car hauler.
And do not for get the price, it has to be right.
