Trust me, list price on those replacement parts, especially important ones like motherboards and displays is WAY more than the total cost of a used G70 at those sort of prices. I wouldn't be worrying too much, just make sure it's cherry to start with, if you can.
Since the G-70's keybed is only shared with a few other Roland products (if any), I'd be concerned about the availability of replacement key contacts/strips as well.
All it takes is a spill of soda pop, especially Coca-Cola, and key contacts are history...only goes to show, that not everything goes better with Coke.

You were wise to buy a back-up G-70.
