After much deliberation, I decided to order an 8-foot portable double barre from the Ballet Barre Store. I liked that the barres were advertised as lightweight and easy to put together. I also was pleased to see they have a 30-day return policy — I would just have to foot the bill for any shipping it needed to be returned.
Both barres are adjustable, and the higher barre can go up to a height of 45 inches. Compared to similar style barres, the $135 price tag was fairly inexpensive. I did a bit of research on the company behind the barre, Vita Vibe. They also have a 5-year warranty on their products for full replacement or repair, which makes me feel all warm and fuzzy inside.
After placing the order through their site using PayPal, I received the barre in about a week (but it was during the Christmas rush, so its possible your order would get to you sooner). The package was long a slim and barely fit in my station wagon! For those of you ordering longer barres, it might be wise to ship directly to your studio if possible.
