I took a 2-day class that came with my Gammill at the dealership in McKinney, TX. It was great. The class was free but since I live near San Antonio, I had to stay over at a motel. The expense was well worth it, however. Also, I have had several questions since then and the dealership is very quick to get back with me and everytime answered my question to my satisfaction. I would suggest that you first contact your longarm dealership and see what they have to offer. Every machine is slightly different and I think it's probably a good idea to take a class geared to your particular longarm.
