Ed,
About $50 to $60 bucks a slot ( wirecut = - EDM),=20 this was my first quote and I have yet to look for alternatives. This is = still=20 cheaper than a RX7 9:1 rotor.
 
BTW $270 US is not the cheapest price, = I only paid=20 $273 Aust ( I believe with a 70% mark-up) and the exchange rate is = 77c in=20 the US dollar. So a good price to you chaps is $210 - 220. Got to shop=20 around.

You can run the renesis rotors if you = get the=20 apex seal grooves milled deeper to accept the 86-95 apex seals, or the = 74-85=20 3mm seals. The Renesis seals are not tall enough to pass over the = exhaust port=20 without warping and breaking. You=20 also need to run the 86-95 corner seals, not the Renesis corner seals. = (there's a metallurgical conflict with the side = housings) 
The front and rear counterweights = from the=20 Renesis engine to balance the rotors are = available.
