I suggest you go to this site I found on Google: http://www.tumbltrak.com/equipment/2:4:80/ballet-barres-dance.html?gclid=CIiTtoSq958CFQli2goddXVWWg
Their cheapest barre is $239.00.
If you want to make your own ballet barre, go to this site: http://www.wikihow.com/Make-a-Ballet-Barre
I made my own ballet barre, and it is VERY sturdy! (:
