Wow I think I am getting motion sickness watching that video. The only problem with that one is cost. The one I build would cost less than $100 dollars. Many different designs out there some good some bad. There is a tread on AT that shows many different ones. I would give the link but I can't get on at for some reason.
hahah i hear ya! AT has been down just about all day from what I know. That last one the biggest cost I think he's got there is that Ryobi stand. Getting a lot of ideas from what I've seen here and off of your plans. When AT fires back up and if you find that thread, post it up.
