They are higher than Mighty Mite because they are just Mighty Mite necks that some guy does the fretwork on.
My advice is to pass, get a neck from Mighty Mite, and pay a local lutheir to dress the frets when you have him install the neck, that way a pro can shim it or whatever else may need to be done to the final setup.
