The one that we sell, designed by JM Products, is very popular, and has gotten good feedback from our customers:

See the installation instructions here: http://www.pelicanparts.com/catalog/images/jm_prod/targa_install.pdf

It works very well, because it uses an existing soft top frame. I'm not sure of the market for a complete replacement, but if you make one, we'd be happy to put it in our catalog...
