I don't know, I've paid $150 plus an 18% tip for a 50 minute massage at a resort in Upstate NY. I did also get access to their steam room, sauna, whirlpool, mineral bath and gym for the day. I only used the steam room.
I would probably look at as $183 for an hour shop since I'll pay for a massage anyway.
A good way to get a cheap massage is to call a massage school. They have to do a certain number of massages to get certified. I used to get an hour massage in Dallas for $25. Of course the proficiency of the masseuse varied.
