Buy at least one strip die for the size you generally cut, maybe 2 1/2” or 3 1/2”. Then buy the HST and QST sets that go with the block size you like to work with. A Qubes is a selection of common does that make 1/2 and 1/4 size blocks of the Qube type. For example, an 8” Qube makes 2” and 4” finished blocks with squares, rectangles, flying geese, HST, and QST for that size. Handy if you do lots of basic geometric shapes. I have a number of strip sets in various sizes, a 8” Qube, and a 12” Qube. It gives me pretty much everything I need for blocks based on 2,3,4, and 6” finished pieces.
