Bill as I'm sure you're already aware, there are several choices for a replacement.
Purchase one on sale with the help of donations starting with the people that took advantage of the old hoist when it was available
Purchase a chain pulley at 1/3 the cost.
Rent one when needed for the same cost as a chain pulley.
Find a used one on Craig’* list, EBay, etc for a lot less with the help of donations.
Split the cost amount members in your area that may have the need for one in the future.
Those are the more feasible options.
By the way Bill, NICE TOOL BOXES!!!!!
