I am also shopping around for a good trike builder, I just talked to Kevin with Horizon in Clarksville, AR, they do CSC, Hannigan, Motortrike and Roadsmith. They build an average of 5 trikes a week, have all the kits in stock so they don't charge for freight on the kits. I'm pretty sure they are who I will go with, horizontrikes.com. They have a nice web site where you can spec the build of your trike and they give you a turnkey price right there.
