Call Mcclain Trailers out of Houston. (713) area code. Not the sexiest but good quality.
I have only bought one trailer from them (trip axle, alum, bolt together, elec over hydrualic brakes for a 30ft go-fast). Their customer service has been outstanding for the wearble parts (straps, bow stop, lights,,etc)... Previously, I have only had experience with welded steel trailers for 2 step hulls (Eagle) and the Mcclain is very high quality for the $$. So far I have been impressed.
If you choose to work with them make sure you get the bunk configuration you want... I prefer the 2 long keel bunks from the middle to the bow of the boat for easiest loading- especially by yourself. Regardless of where you purchase- make sure any manufacturer puts the brake actuator as close to the hitch as possible. This comes in very handy on shallow lake ramps that force you to back in very deep to launch. I learned that trick the hard way... Just my .02$
