Those TSPOF systems are really nice. I like te simple "flip" feature. The KO3 seems overpriced compared to the other models, but I see they just dropped the price by 1/3. How do you like yours?
I got a JET cyclone separator with 20-gallon tank at Woodcraft for $80 ... $250 off the regular $330 price. It was a Door-Buster price to get folks to come in. I was there early before they opened and the four of them they had were gone 30 seconds after opening the doors. I was one of those four. I'm going to hook it up to the bandsaw and some other woodchips and sawdust creating tools. I really like the window on the tank, so you know when to dump it.
TIP for those with portable sharpeners:
Use a piece of butcherblock, or a butcherblock cutting board for a solid and heavy base to mount the sharpener on. You can often find a used 20# butcher's block at a thrift store for $10 or less. Youb can laminate one up from 2X4 lumber, too.
