P3D RBT Cameras - Where to find used? (or other compact autoexp?)

["J. Christopher Bell" <jxopher@xxxxxxxxxxx>]

Wise and Noble 3D Experts,

I'm looking to acquire a 3D camera. I tested out a stereo twin 35mm Canon
rebel G rig, but it seemed so huge and awkward and breakable, and hard to
keep aligned. I bought a used Realist, but I'm not sure I can do separate
exposure metering and stay sane. For me to stay sane, I think it needs to
be easily handholdholdable (compact) and easily storable (no sensitive
attachments, splitters or other things to snap off) and *autoexposure*.
(BTW, no lenticular-types). The RBT Cameras look awesome, but autoexposure
versions start >$3000. Ack!

1) Can you recommend sources for used RBTs (other than online auctions or RBT)?
2) Any other suggestions for easily handholdable/carryable *autoexposure*
   stereo rigs other than the RBTs?

Thanks,
      -- JX

P.S. My birthday is the 29th. If someone friendly and well-to-do wants
to send me an RBT for my birthday or give me a special deal, just say so! :-)
