I like Harbor Freight, for the most part... I'd describe myself as a bit of a "convert" from thinking of them as a seller of "cheap Chinese crap." For your basic run-of-the-mill stuff, the price is hard to beat. If I were running a precision machine shop or cabinetry shop, I'd look elsewhere... but for the basics, they are great and reasonable.

I have one of their two-wheeler dollies that I've been beating the crap out of since using it to haul piles of limestone rocks for a wall when I lives in Texas in the late 1990s, and it's still going great. I have one of their rotary tools (Like a Dremel drill) that I use to drill holes in rocks... no complaints.

I hope the blade sharpener works out for you; looks like it won't take a whole lot of refurbished blades for it to be worthwhile.
