I don't - but if you find 'em, let me know so I can let others know.
FWIW, we only use ours to heat air for driving fluidyne engines (no steam).

I'm not all that interested in just a collector per se however if you come
up with a collector and a steam or Stirling engine that drives a generator
and produces power and is not terribly expensive and all you have to do is
add water I'd be interested even if it produces only a few hundred watts.

I think you would find a lot of takers, including myself. I would make
up a list of possible practical uses for them, and keep adding to it.
Also would consider carrying frames and stands, plus accessories.
Something to place objects on the focal point. Containers, food
holders etc. I would like to make char out of leaves and sticks, but
am no allowed to burn. Ideally there will soon be some sort of small
heat engine marketed that will make electricity from your dishes. You
tube would be a good place to advertise, plus sites like this one.
Eneco is working on a chip to directly convert heat to electricity,
then there are Stirling, and steam engines.
Good luck with your endeavors. We need thousands of people like you,
producing small energy products.
All the best,
Ron Wagner

as per http://solarcooking.wikia.com/wiki/Indirect_cookers
In 2008 John Grandinetti publicized his Evacuated Tube Indirect Solar
Cooker. Grandinetti's design replaces the finned pipe with an
evacuated tube solar collector as the collector element, and uses
vegetable oil instead of water as the heat transport medium. With
these changes and some other refinements, the design provides a
practical solar appliance. Tests have indicated the unit can reach
cooking temperatures (300°F) with 1 hour of morning sun at tropical
lattitudes. Cooking, water pasteuization and autoclaving can be
readily achieved throughout the remainder of the solar day, with
cooking times similar to an electric stove. Frying, baking, boiling
and steaming have all been successfully accomplished.

Go for it, lot of solar applications could use this product!
