Having learned my lesson with buying low priced tools a few times over on the Ryobi brand, when purchasing my newest addition, I went with something a little higher tier.
This is a DeWalt grinder, along with a selection of disks that can be used for cutting and polishing. This tool is going to come in VERY handy once I start working with metal for the MattMobile frame. I think it's also a pretty handy tool to have, as it can do a lot of stuff. I'm glad to finally have one of these in my arsenal.
