G.R.
i have 2 one i brought in craiglist (mini stepper) for 15 dlls. and works great and the another one also works great but have a little more tension so you do a better work out is the golds gym mini stepper i find it in walmart for 50.00 i do it while my kids take a nap and i watch tv.
with the golds gym maybe the tension cable may broke but they will send you one free it takes 3 days just fill the form online
i brought the mini stepper because i don't have space for a large equipment
