I know it sounds douchey but you guys are getting
really lazy. Do some research yourself.
But I actually own a flycam nano. Though a glidecam would be better, the flycam rly isnt that hard to balance. Obviously the first time is hard, but after you get the number of weights right and the general positioning of the sled its not hard. It is a pain in the ass to have to slide it 1 mm and then lock it down again, but its worth it to save the extra couple $100 bucks in my opinion. The other problem for me is the bottom part of the sled, under the pole, is really sketchy. I remember trying to tighten it as much as I could and it actually removed the glue from it and it came loose. I had to re-glue it myself. However that might just bee because mine is an older version, or I just got a lemon.
This guy emm, at cheesycam.com did a bunch of reviews of the different stabilizers out there, definitely check out his flycam vs glidecam video. Also I'm 100% sure that if you googled it you'd find a bunch of threads at dvxuser or something asking the same thing
