Beam splitter options: please advise

Hi.

I would like to learn more about beam splitters, or any means I might
employ to make stereo pairs with a single-lensed camera. I made a very long
drive to the National Stereo Convention a couple of weeks ago and
invistigating beam splitters was at the top of my agenda for the show.
Unfortunately, I didn't find any, although I did find some some of those
dual-mirror and prism splitters (perhaps not true beam splitters - I don't
really know). I held one of them up to my eye and I seemed to discover that
leveling the device was essential. Is that true? Is that true with a true
beam splitter? My hope is to buy a Pentax beam splitter, as I was told that
Pentax is the only manufacturer presently making them with any regard to
quality. However, if it turns out that even a true beam splitter must be
held perfectly level for all exposures, the limited usefullness of the
device might make the investment in one unwise. I would love to hear from
any of you out there who have any experience with splitters or any other
means to convert single-lensed cameras into stereo cameras (and BTW, I am
well aware/experienced with sequential stereo exposures made using a rail -
it's active subject matter I want to capture in stereo!).

Thanks for your time!
