MaxTool via eBay offers the Durostar Eco-Shredder Chipper for $134.99 with free shipping. That's $25 under our March mention and the lowest price we could find by $50. It features a 2-horsepower motor and 3-cycle shredding.
I've purchased a couple of these units in the past and have had to weld the feed tube on each unit more than once. Its a design flaw and will make the unit unusable unless you know how to weld. It will chip up to a 3/4" branch if you feed it slowly and turn the branch and have sharp blades. Otherwise you will spend a lot of time burning the branch instead of chipping it. It isn't a bad unit but I am looking at my next purchase of a similar product from SunJoe at about the same price.
