It took a dark stormy night but I finally looked into the Dyna Myte 2400 Upgrade.
Attached is an Excel SpreadSheet with links, notes, and prices.
A short summary:
Without looking for sales/deals the cost for everything is about $500.
If I recall we have a $450 budget I'm good for the extra $50.
After building the BOM I found a company that has an upgrade kit, see spreadsheet.
The upgrade does not appear to be as hard as I had thought.
I need to look the machine over and verify it's motor specs.
I think we could make purchases next week if the group agrees.
Is there a Tax ID?
Exciting,
Ray
