Ron has posted a video saying that Fastcap has some left but no new production so if you want one you will have to see if they have any left or make them your self.https://www.youtube.com/watch?v=_pzG_I76fHM
Depending on where you live and other factors determine if it would be practical to get the Moreland Ultralight plywood. I'd like to get just a couple of sheets but have not found a way here where I live that is reasonable.
I have the plans for the miter station and found a few issues with them, can not speak to the other plans. I'm not planning on building his version anyway, it doesn't fit my needs and space constants but still worth the $10 just to see how it was done and to adapt some of his ideas to what I need.
I'm now a big fan of Festool. I'm limiting myself to just a couple of thousand $ every year. I love the MFT and what the hole pattern along with dogs brings to both working and clamping. I've gotten the extension table for it this year along with the Kapex, and I hope to add another sander sometime later this year. I have just a couple more of their tools I'd like to have but time and money will dictate if and when they might happen.
The Festool system is designed very well and it is a system so they took the extra step to get to that point, most other companies have not and do not. Besides if they were cheaper everyone would own them and what fun would that be?
