One of the best 100mm APOs out there most likely.
A real low price.
There was also a G11 for about US$1250.
Then the Orion autoguiding package, a 2nd hand DSLR and you may just squeak it in (pehaps another $400-550 needed).
Here's an example of what modified 2nd hand DSLRs go for ( I know its sold its just an example) (add say $100 for shipping and insurance -no GST as it is under $1000)

One tip on dew heaters - I bought this simple wrap around dew preventer for my refractors. I basically is the same material as those windscreen sunscreens. A bit of velcro, wrap it around the tube where the lens is when you first setup and it keeps it a tade warmer than the surrounding air and prevents dew for a long time. Cheap as chips.
