I have three (3) modified rejectors and 4 ones with the relay+ Jones plug.
The ones with the relays were made up by http://www.shafferdistributing.com
There are supplier for parts and manchines,
here in Columbus OH. We used them on soda machines once in awhile that wanted free vend on occasions.
Nothing is really pretty, all are used, but we were a vending business after all.
I would prefer a money order, but will take a personal check.
I still have a few assorted changers and a Coinco tester I would like to get rid of.
Also Jones plugs that I cut off from dead changers, about a dozen Coinco plastic
PM me whan you want more details.
