My 1st Shoebox Max….I sold it before I had to repair it.
My 2nd Shoebox Max..I tried to fix it, but salvaged the motor..
The current Freedom 10 I do not use much but Tom gave me a bunch of o-rings in case I have to.
To answer your question, I think everyone is going another way.
More is the pity..
BTW Tom is under contract with NASA..
