Frank,
let me kick this off. I have used the SBIG gear, and it is nice, heavy as heck, but nice. The self-guiding is good too, and I loved this part the most perhaps.
The QSI line appears to use a fixed in place off axis guider, which is slightly different to a dedicated built in chip. Not saying it is no good, just that if you are going to an OAG why not get one and then get a camera, without having to buy the QSI.
Another option is to get the smaller lighter cameras now populating the markets, SX, or QHY, and retain the guide-scope.
The SBIG stuff works, and well, but the penalty of weight is up there, at least it was with the ones I had.
