Aftermarket Bellcrank Rear M/C

Anyone know of a good aftermarket source for a bellcrank rear master cylinder, other than Mikes XS? I have no problem with his (its actually exactly what i need) but I can't find any even remotely like it on eBay or google. It's like they don't exist other than that one.

Did any other bikes come with this style or are most all bikes equipped with the pushrod type mechanism?

Update: Just purchased the Mikes XS one, since nobody had any alternatives to offer..

Side note, I would assume most garage-builders use the factory M/C's push rod and modify it to pull on the bellcrank lever? I do not have that part so I will be fabricating something from some hardware and steel rod or else find something to modify.

Mounting the M/C will be figured by the length I have available, given where my rear brake line fitting ends, and welding a small plate that is drilled to the centers of the holes on the M/C and bolting the whole assembly to the bike with some stainless hardware and nylock nuts. Ain't this fun?
