I still can't believe there are models that still use 9V batteries, though there are probably some weight advantages with a small light battery so it does make sense on some level.
I will be interested in a head to head with the Makro Racer. I'm liking the G2Plus. I will wait until I see some head to head comparisons. I've been a bit surprised at so many Racers becoming available so quickly after customers use them a time or two.
