I'd recommend saving your money and get a two or three filter set of
fixed ND filters. The big problem with the variables is that they do
nasty thing on skies with wide-angle lenses. A variable polarizer is
two layers of polarizing material, with one rotating.
The expensive ones have some additional complexity engineered in to
counteract the nasties, somewhat, but they are still there.
