STL is a good camera but its full frame 35mm sized and requires a largish focuser and largish corrected image circle. I wouldn't recommend it unless you had a high end scope that can cope with it. The advantage though is it includes a filter wheel and self guiding
and prices are lowish (it used to be a US$7500 camera).
The Sony 814 chip is the same size as the 694 chip so it will offer the same FOV. FOV is chip size not pixel size. Pixel size affects how much light hits on each pixel.
Both have similar QE (694 is a bit better not much) 3.69 micron pixels are getting pretty small though. A lot of images you see on this site are KAF8300 (5.4micron pixels or Kodak chips at 6-9 microns usually).
694 is the most sensitive chip around except for the older SBIG ST10XE (there's one on Astromart 2nd hand for under $2K at the moment).
Importing incurs GST if over $1000. Usually there is no import duty as GST replaced a lot of those. So add the likely shipping cost (often around US$300) then add it all together convert to Aussie dollars add about $100 and then 10% for GST to get a final cost.
There's an ST10 on the classifieds here for $1800 and it includes a filter wheel and a few filters.
