An interesting choice..( I can hardly get my students to dance that here,in UK. )
Your chances of finding a male partner in that Div. may be a little more difficult, as most in the States look upon it as a competitive style. The American style will give you more social outlets,unless of course, you are on a campus where there are all styles from which to choose .
The chain school prices are quite similar and some are even lower than those within the same Org...Indies are frequently cheaper ,but with less social activity .
My suggestion would be to get into Class work first.. try the different styles, and then make your choice on practicality and cost.
