If you have an oxy-acetylene torch another option is to make your own. I followed the instructions here and the process is pretty straight forward. I went with a nominally heavier bar (7/8") than stock. With no sump to clear in my setup the shorter length increased stiffness as well. I haven't found the cornering limits yet but no appreciable roll so far - everything's taught and flat.
Happy hunting.

Thanks for the link and bringing up the old thread on this. Looks like a good idea.
