They have a really good deal on the glidecam 2000 pro on ebay, going for like $180 with a day left.
Honestly, I don't understand why people here on NS dislike flycams so much. Yes, they are not nearly as well built as a glidecam, but if you treat it well it will be plenty durable. I'm probably going to upgrade to a bigger camera/rig before I'll have to replace my flycam nano. It's much better than just going handheld. It's really not as bad as people think. You don't need a $500 glidecam and a L lens to get good looking video.
As for DIY glidecam/flycam, there are a couple of threads here on NS (searchbar...) and some on youtube. If I'm having a hard time getting my flycam perfectly balanced (yes i know a glidecam has fine tuning and would be easier) I can't imagine what a pain in the ass it would be to balance a DIY glidecam. Another option would be a fig rig. (you know the things that look like steering wheels with your camera in the middle?) They work surprisingly well. Totally different type of stabilizer than a flycam/glidecam/steadicam, but you might want to make a DIY one of those. There are tons of tutorials on youtube about diy fig rigs. It would be pretty cheap to make one out of pvc pipe, you might want to try that out.
inb4 "glidecam /thread" if you have the money to get a glidecam, get one, but if its the flycam, or nothing for half the season, get a flycam. What matters most is that you can actually film and not worry about saving up for more gear (duh)
hope this helped.
