If you're just looking to dance going for full body would be your best bet. Cheapest is a used vive and 3 tracking pucks. There is no alternative for full body than the pucks except I guess for the kinekt but everyone that tried that has since got sick of it and bought the pucks. Pucks do need vive base stations so it's cheaper and easier just to get a vive set than to fuck around with hybrid setups.
