[photo-3d] Externally twinnable SLRs

[Peter Davis <pd@xxxxxxxxxxxxx>]

All this talk about twinning Ricoh and Pentax cameras has gotten me 
wishing.  I've been using a twin point-and-shoot rig for a few years now 
with great success.  I'm about ready to move up to a twin SLR rig, but I'd 
like to find something that's lightweight, has auto-exposure and auto-focus 
(let's not debate the merits of these features again), and is reasonably 
rugged.

So what are the best available models to use for this?  I believe the Ricoh 
and Pentax cameras under discussion to NOT have auto-focus, right?  I've 
heard people praise the Canon Rebel X for this purpose.  I know these are 
very lightweight, and they're fully automatic, but I've heard conflicting 
reports about the quality of the lenses.  Also, I'd have to figure out how 
to shoot flash shots with these.

Are there other really automatic cameras for under $500 each that people 
would recommend?

Thanks,
