Below is a list of our best-selling products that we almost always have in stock. Generally, these units are purchased from private practices and in good working order when we receive them. Despite this, we fully inspect each unit, proactively change out parts that show wear or are most likely to fail and calibrate each unit before packaging for delivery. All units are given a 6 month comprehensive warranty and current customers get a full one year warranty. Most units include an on site visit from a professional trainer. If there is something you are looking for not on this list, we know where to find it!
