HF100 and HF10 are technically the same except for the internal memory. But HF11 is slightly different with the 24Mbps .
Looking at the comparison here

Just choose HF10, HF100 and HF11
HF11 is 98% the same as the 2 other model, but these 2 charts, luminance resolution and chrominance resolution seems to perform better, although I don't know what these 2 charts represents. The test small ISO image also seems to produce more details although it's seems to tends blue.
I tried the Borderlinx calculator, there is some kind of taxes involved, think I'm stinking to VPOST.
Just one question, does the power charger able to switch between a 110V and a 250V?
