Places that train standup and ground besides the ones you mention include 5 Points Academy, Team Coban, Class One MMA (Brooklyn), Renzo Gracie Fight Academy (Brooklyn), and Evolution Muay Thai.
NYC is crazy expensive. I wouldn't be surprised if all of them are at least $200/month for both standup and ground classes. Some of them include weight training equipment or crossfit type classes as well.
I think the newest gyms are Team Coban, Renzo Fight Academy, and Class One. They all opened last year.
Try out a free class or two from all of them and base your decision on that and the atmosphere/vibe. Let us know what you end up going with.
