X-POLE BABY!!!!??(dance poles)??/?

Question

Alright i am buying a X-pole and i don't know what size to buy 45mm or 50 mm i don't want to have to turn around and buy a knew pole after getting more advanced with harder moves. Money-whats the prices, the one i found is $299.99 plus shipping and handling like $339.99 which is not very budgeting. Any cheaper places that will get me a chrome x pole ?? and does it have to be sent to my house?? and bought with a credit card?
