Here's the one I was thinking of.
US$2775 107mm F6.5 with reducer giving F4.9 plus a flattener, rings, case and good focuser. Hard to beat.

For a bit extra you get larger reducer and focuser.
This'd be the one I'd go for. This is like a dream come true for an astrophotographer in that price range.
Shipping is most likely US$350 to $400 and GST on entry would be about AUD$300. Bank Wire transfer costs about AUD$25 and the US bank takes an extra US$25 from the amount sent.
