roll bar choice

I'd like to add a roll bar to my bugeye this fall and wonder if the MM
bolt-in one is any good.  I called a few places and got quotes of about $300
to make up and weld in a custom one.
Experiences? Suggestions? Warnings?

It won't be a SCCA legal bar, as I want to be able to mount the hardtop or
soft top sometime in the future.

Does any lister know of a "bolt in" one languishing away in a back yard
somewhere?
