I believe stronlgy in massage and get them often.
I sometimes go to the massage school and get one for $25. Check to see if there's a school near by? It may not be the best massage ever but I think it's really worth it at the cost.
I typically will get a few of those and then periodically fork over more for a massage with Twila, the best masseuse on the planet, who gives outdoor massages at the beach here on Maui. Anyone coming to Maui should ask me how to find her and treat yourself to an hour of pure HEAVEN.
