I have gone to a very good clinic during their 'Community Acupuncture' times. And there are four or so other places around that also offer a very similar type of service. These are regular private practice clinics where they do see clients individually. They just offer this option to help get acupuncture to people who otherwise couldn't afford it. And, it is not as thoroughly personal, but they do give some individualized attention to assess what to work on during that session.
As for cost, they offer a sliding scale with a minimum of $20 and maximum of $45; you pay what you feel you can afford. The initial visit is more like $30 to $60, though, as they do an intake with you to get to know you and your issues a little bit.
It's really quite wonderful. It's held in a quiet meditative space. Each person can come @ any time during the hours open, and stay as long or as little as they like. There are multiple super comfy recliners, meditative music, a fountain, and very little quiet talking.
I went three or four times. It definitely was very helpful for me.
