Like all things Surface, Microsoft's Pro Type Covers are pricey. In fact, it's tough to find an official Microsoft Surface Pro Type Cover for less than $100. Thankfully, a set of third-party manufacturers have stepped in to offer some more wallet-friendly options, and for less than half of what Microsoft charges you can get a decent keyboard cover for your 2-in-1, whether it's the new Surface Pro 6 or a Pro from a few years ago.
