yes, I once saw a cheaper way: a simple  rod (the one I saw was "L" metal,
but it could also be wooden) with holes drilled at 3 distances (to roughly
adjust the stereo base to "people", "architecture", "landscapes").
In the "people" position (base = about 6 cm) the reflex cameras were
horizontally scaled like the parallel rods a loose "letter Z". The owner
said 1 inch difference in distance from subjects is meaningless.  The bar
also had a pistol grip (in that case I should better say a "broom handle").
Despite the twin cable release, the phographer told me that sinchronisation
of shutters was still unsatisfactory, so he had to hold firmly everithing
and he could safely take pictures just of nearly  still scenes.  He had his
device made by a repair shop, but you won't find any difficult
home-crafting yours.
