NWR: Can someone recommend a dance studio/gym/?

Can anyone recommend somewhere to take dance classes that is not terribly expensive?

I'm up for anything Hip Hop, Jazz, Ballet, Modern, etc.

I'm really more interested in it for the exercise than for putting on a show, etc.

Preferrably in Suffolk either near my job in Melville or my house in Ronkonkoma.

TIA for any reccs!
