I think Power King is the way to go for parts. I was purchasing parts from Heartland Equip. but other owners have expressed good experiences with PK and it sounds like their prices were a little better. If you use the search function here on TBN for "Digit", you will find some good, informative threads posted by Digit owners. They are unique machines and very handy to have around. My only complaints with the machine are travel speed and traction. If it's wet/muddy, you'll quickly learn how to drag or push yourself around with the boom.
