I would stay away from Farrell because his pieces are WAY too expensive for what they are. Apollo has a few salons in California (Costa mesa, Glendora, LaJolla, and San Jose). Apollo is expensive too, but not nearly as bad as Farrell. I would go to Apollo about once a month and it was $50 plus tip. Just be aware that these places are not your friend and they will do everything they can to keep you tied down to them. They want to keep you in the dark about what they do and make it seem like rocket science. The monthly fee isn't the entire problem, its the fact that they want to sell you a new system every couple of months for about $800. If you don't agree to buy one then they try to tell you how the thing will basically self-destruct if you leave it for too long. These places are full of crap and unfortunately a lot of people that go to them believe every word they say.
