I've got a CDC V6.0b - It's great (my first one had a problem with the fans not working when charging - though it still charged properly). Got it replaced - and the new one is excellent - 20amp discharge, no false peaking, resistance measurement.
However, I am now looking at the Yokomo for 2 reasons - temp. charging and upto 9.9amp charge. The CDC charges up to 7amps - if it would charge a little higher I would stick with it.
my 2 cents
