I'm looking at picking up an M18 at the moment, and tossing up between grabbing it with either the Arri 1000Hz ballast, or the Power Gems 1000Hz ballast.
Being in Australia (well, technically I'm over in Bollywood at the moment, but I'll be home in a month), I haven't encountered the Power Gems gear before, so I'm a little wary of buying sight unseen. But it appears the Power Gems draws a little less amperage than the Arri, and it's also physically a bit smaller which could certainly help out for transport.
So I was wondering if anyone has any thoughts on how the two compare? With the quotes I have at the moment, there's a $500 premium for the Arri ballast. But I'm also conscious, that having everything Arri, might help with resale if things change and I need to sell the light down the line (though I honestly suspect you'd have to pry the M18 from my cold, dead hands because it's such a useful light, so maybe that's not a huge consideration, but an emergency one).
I'd certainly appreciate anyone's thoughts.
