cheers guys. thanks for all your feedback . I think i have made up my mind and stick with the Hutech 40D. The banding issue only happen with one particular user which im sure will be still under warranty from Hutech.
WOOHOOO!! HUTECH 40D here i come! I know houghy, the Cooled DSLR will be a better choice, but even so, the Hutech 40D is still cheaper than the Cooled DSLR, it is a higher model with live vieww
once again, thanks for all your input !
