This Exerpeutic treadmill is designed for people doing injury rehab, low impact and varies in speeds from 1/2 mph, up to 4 mph.
I had it for hip replacement therapy and no longer need it. The unit is 100% perfect condition. Clean, and no issues at all.
This is on Amazon for $900 plus shipping. This is an excellent price. Here is the unit description on Amazon at $899.
