Greg summed it up correctly except for a couple of minor things.
There is no "Better Electronics". Sbig, FLI, Apogee, QHY etc make great cameras. You need to look at "Features", which is what Greg is probably trying to say. All will produce low noise, high speed images, and cooling is similar, all above -50 delta these days. However, your noise after a certain point doesnt make much of a difference, hence, as Greg said, look at the second hand Sbigs as well. The CCD's are smaller again, but they are great cameras, and some really sweet deals out there.
But if your stuck on the 8300, then i suggest you look at any camera with that sensor, and see how the image scale of objects look like.
I use my QHY-9 on my CDK, and that has a much longer FL than the 10" RC, and i find it fine. It is a little on the smaller side, but i am pretty pleased with the CCD overall.
QSI also makes great cameras, and again, another choice.
So for now, just check out the images produced by the Kodak 8300 CCD sensor and think about it.
