I am totally over buying cheap stuff and trying to "DIY it." Most of the time the hassle is not worth the results--and you end up with a product that is quirky at best and makes your clients question if they have hired the right person. This little dolly, less than $100, seems to be a great little product that is well-built and will certainly offer more than $100 in production value the first time you use it. If you use HDSLR's, GoPro's or other small cameras, check out the extremely portable Pico Flex Dolly
