The LQS near me rents out an Avante and a Sweet 16. To rent the Avante you take a $50.00 class. Their hourly rates are very reasonable, $75 for 4 hours or $125 for 7 hours. You provide leaders, batting, and any marking equipment (pounce, rulers, etc.). They provide thread (they will order any colors you need ahead of time), and have a selection of pantographs and groovy boards. The Sweet 16 is even cheaper—I believe a $30 class and $15.00 per hour rental.
They are a full service LQS and machine dealer, so my guess is that they are making money by getting people in the door. I’m sure a lot of people renting the machine end up buying fabric, supplies, etc. while they are there. I am going to take the class in the winter this year.
