Malibu Pilates

I've been considering buying this product, but was wondering if anyone here has one or has used it. I had knee repair surgery a year ago and I can't squat or do exercises like walking/treadmill, has to be I guess low impact on my kness, plus I'm overweight. I use to love to walk, but now that's out I need something. Doctor suggested bike and elliptical (sp), but I can't buy all that, need one piece of equipment. This looks like it works all parts of your body any maybe not put to much pressure on my knees. I also have arthritis all over my body, so I need some help.

Would love some advice or suggestions from people that own or have used this.

Thanks,

Denise
