Making a power wheel

[vadrip]

Being that there's usually a way around expensive exercise gadgets I was wondering if there's anyway to make a less expensive power wheel because the power wheel is over $40 and I don't want to spend as much money. The power wheel is listed as 14" wheel (solidly constructed with foot pedals and extended foam cushioned axle to accomodate both hands and feet)
Velcro toe fasteners and latex looped heel fasteners. So what say the people here is there a way around buying the wheel or just suck it up and buy it.

I found a lot of exercises with a power wheel are doable with a swiss ball so there's no need for me to buy or make a power wheel since a have an exercise ball.

I already have a toner wheel which is similar to a power wheel, but you can't strap yourself in it and is much smaller than a power wheel which makes it unable to put your feet on it to do exercises with. Also, you can also substitue dumbbells or barbells for power wheel exercises too.
