also do you find enough guidestars @ f/8 ( i assume the SBIG sensor for the guiding is more optimised for higher sensitivity than other guiding cameras)?

I dealt with both the Australian representative and the management of SBIG both before and after the takeover. Communication was generally good throughout the process. The whole process was rather lengthy though with it being about 12 months from the time the fault was first reported and three trips back to the States and then the replacement camera. That was the most frustrating thing. The process was also complicated by the takeover of SBIG by Cyanogen. I have no doubt that SBIG went to great lengths to alleviate the issue and did lots of testing to ensure the new camera would not repeat a failure.
The guiding prism is in front of filters so it is like any other ST-i or lodestar guide camera. So it is not any more sensitive it is just a better solution than having a separate OAG and guide camera. It relieves an element of back focus that would be eaten up by using an separate OAG.
