For sale is a F75 in great condition-it does'nt have the upgrades as I felt I really did'nt need them because I have both the enviro covers for it and I'm glad I did'nt because apparently the rubber gaskits are cracking--this machine works as it should and comes with manual-enviro covers and original box--I'll also throw in a pair of used gray ghost original head phones-they work good but the cord is a little stretched out--I'm asking $650.00 shipped in the lower 48--postal MO will work the best for me-Thanks-Mike C...AZ
