Yeah, so I have to get my GG guys, and really need some arguments on which one to go for. I'm choosing between the Optosigma 1500grit and the Nikon D. I know with the Opto you have to buy a Condenser also and Nikon D you don't. I haven't seen too many grabs or video from either one. Just a few here and there. Give me a good reason for going with one or the other.
