Actually a lot of things at Rockler are cheap but also cheaply made compared to other similar tools and jigs on the market. However, nothing online indicates charges for upgrades, just in a couple of cases difficulty downloading and installing an upgrade. Still researching it. When I get a couple of weeks that I can allocate a significant amount of time to the trial version, I will download and use it to see if it is easy to use, quick to learn, and accomplishes at least basic woodworking drawing/design capabilities. I can still use Sketchup with the free 2017 version so I'm just looking at the future.
