double comment derp but seriously they're not THAT bad. I'd rather have a glidecam pro (no fine tuning) than my flycam for durability/longevity, but once you balance it a couple times its not hard at all. If you have the money go for a glidecam but if you just take care of the flycam and have patience to balance it its perfectly fine. With a quick release it doesn't even matter unless you're changing lenses every 10 minutes. Also, with wind mine sways a bunch so I have to correct it with my hand, but if you put more weight onto it it would probably help.
