There is a lot of info available on the magnabend website about how to build one, so this is also in the mix. I did some research and I think I can build one for < half the cost of new one. Of course, that attaches no value to my time and some of the details like the angle setting device and the rather elaborate hinges make it a pretty large time sink. For me, I'd guess it would take every bit of two weeks (so four actually) to build one if I had all the material/ parts on hand at the start. I have only seen one on CL around here and, in hindsight, I probably should have jumped on it, but I didn't. Like so many things, it looks like they all come from China now and are rebranded for various end sellers. Not sure if the RW ones are domestic or not. They were the original sellers of the technology in this market and, now that the patents have run out, there are lots of people in the game,but most of the offerings look like the same thing with different stickers. Doesn't mean they are bad, just that the price and warranty become the dominant drivers since the products are all the same (it looks like). Thanks to all for the feedback; keep it coming.
