I rent the Gammill at my LQS for anything larger than a cot or lap quilt. To me, not having to wrestle and grapple three layers of quilt is worth every penny! I had one lesson with the owner and luckily took to it like the proverbial duck.
More is charged for the first hour (loading the quilt on) as presumably the time of one of the shop assistant is factored in, then there is a set rate per hour after that.
If you want to use a pantograph you need an additional lesson. It's in use most days.
