Exercise Equipment - Fav. Brand Fitness/Exercise Ball?

I've been reading so many reviews and now I have no idea what brand of fitness / exercise ball to order. Does anyone have any favorite brands? (I will be ordering two balls, a 45 cm and 55 cm).

Thanks so much!!! :hug:

I am on my 3rd stability ball. The other two were worthless. I don't even remember the brands. Right now I have a 45cm one from Lifeline. I got it brand new from e-bay. Love it.
