Hi Michael,
I found this thread for a canon for sale second hand, has been modded so no good for day time use, but is cheap considering what you get with it

Also saw this for sale at Astro buy and sell
http://www.astrobuysell.com/au/propview.php?view=1734 and thought you may be interested.
Cheers
Anthony
