Bracket to mount two DSLRs of Astrotrac?

[michaelmorris]

I like the idea of being able to use both my DSLRs (Canon 1000D and astro-modified 1100D) simultaneously on my Astrotrac.  This would either give me double the hours exposure of the same target or the ability to image two different targets at the same time.

I'm having difficulty sourcing a reasonably-priced  bracket that will allow me to try this.

Any suggestions?
