I sold my SBIG ST-8300C recently - nice, but noisy as all heck, requiring full darks, bias, and flats.
Went for a Sony chipped Atik 314E colour - small chip with small pixels (less than the 8300), but delightfully noise free and adequate enough for my needs now I am using a 76mm refractor. Cooling is non-regulated, but with a Sony, that's not so important compared to the noisy Kodak chips. It still drops 25° below ambient, which for most nights means it sits at 0° or less depending on the season.
I picked it up for $400 in the trader - and that was a steal!
