surface controller Deluxe

hi, im using max 9 and im unhappy with the existing (and old) surface controller...is there any better script? it could be very useful to have an object actually following the surface ( animated surface; nurbs, patch or even polys ) just by dragging it around with mouse. currently its limited to U and V spinner that could be wired to something i guess. but it sucks because at one point the object just decides to fly out, help! :)
