I have a 55" ball, just a cheapy from Walmart. I think it was $10. It's not tall enough for work, and it does leak air. I have to refill it every few days. I've learned that you definitely get what you pay for with those.

Other than that, I love having one, and it helps with my low back/hip pain. I used it a lot last year after my car accident. I will probably get a better one this year.

I bought mine from Walmart - its a Bally Total Fitness ball. Because I'm 5'6, my midwife told me to get a 65 cm one - that way, you can make sure that it inflates enough. She said that its best to get one that, when you're sitting on it, allows your knees at a 90 degree angle.

I've been using mine for two weeks, daily at home, and it hasn't leaked at all - its still the perfect height. Make sure you get an 'anti-burst' one - they might be a little more expensive, but worth it!

I had one from Walmart too. Maybe the Golds Gym brand, I can't remember. I used the size chart on the box though and it was great!!! No problems with it at all.
