Sorry, I should have searched the archives 'before' I posted this. All signs point to 8" as being the most logical contact wheel to start with. I may purchase a 10" later if I feel the need.
I just ordered the 3-Speed KMG-8 with platen attachment (1.5hp 110V) and Switch Kit. Total was under $1.8K so I am still under budget! Looking forward to learning and progressing with this tool.
