Query: Work Really Well but Expensive

These things work really well with the MFT. You can get quite a bit of pressure of these. They work great for sanding, saw, etc. But if you are handplaning on edge, they aren't strong enough but this is an admittedly tough task for this set up. I've also used these on a couple of jigs. Just drill a 20mm hole and you can use these anywhere.The ideal situation would be to own 2 sets of these. There are several times I have wanted more than two of these. Unfortunately, these things are phenomenally expensive. It seems that these things sgould be about $35, $50 tops. The current price of $80 makes one feel they have been taken advantage of in a bad way.
