Most Showhauler dealers will have a rig already available, not sure about build time for a new one on a new chassis sorry. If you call and talk to Lonnie at Showhauler he can take care of you. If you're interestedd in possibly a used one let me know. It's availble at any time and less expensive then new by a long shot
(FWIW I'm selling in it order to get another SH one built).
Personally - I looked at all of them too and prefer the Showhauler. Renegade does nice work as well, I have one of their trailers. But just prefer the design of the SH better. Either way I'd say you should absolutely look at them and make up your own mind. As I've offered others - if you're anywhere near Atlanta you can come see mine if you'd like.
