M&R iDot 4100

Have 2 iDot 4100 machines....one needed a new print head when last used. Not sure they are available any longer or if M&R even supports this model at all. The other worked when last used about a year ago. (on light substrates only, gave up on under base white long ago) Has bulk ink system, adult and youth platens. Has been in storage for the past year. Two machines, one for use, the other for parts?...or both for parts if you have one that remains in use. Make an offer if interested.
