the LQS that closed down used to rent time on the longarm. it was 100 for the class and then 15 an hour for the rental.
i would never rent time on my machine. i have too much money invested and its a critical piece of equipment in my business and i don't want someone to break it.
most likely they would fight me on paying for the repairs and i don't want the down time of having to repair the machine because of some one else.
