chainrings

I'm looking for correctly oriented oval / non-round chainrings suitable for MTB chainsets, i.e. 110/74, 94/58/56 or 104/64 BCD, although 130/74 is a possibility. NOT interested in badly oriented rings such as Biopace / OvalTech etc, but stuff like EggRings, Doval, Osymetric or Rotor Q-Rings...
