Got the TORMEK but by time I got there, the Festool sander was sold...Decided not to pursue the Delta air cleaner..No timer or remote..
Thanks Davis for your insight...Yes all those accessories came with including a grinding stone (often omitted)..Now I understand the sliding nature.
I feel good about the purchase and looking forward to set up and trial....THANKS to all of you!! You helped me make a sound buying decision..!!
