Our Sacramento club meter is owned by the group, being paid for by those of us who contributed to the cost, after it was purchased by Tom Barr. We owners don't have to make a deposit to borrow it. Those who don't want to kick in $25 or so to be a part owner might end up leaving a deposit. At $25 each it only takes 10-12 people to buy one.Oh yeah, also you may be able to join a local club. The one here in Sacramento has a PAR meter that can be used. Personally haven't used it but I am sure there is some sort of deposit required.
