If it was cheaper I would grab it just to experiment with and because I have been looking for one for soo long. It's my white whale. Now that I have replumbed everything I am super happy with the IE IM/stage 2. I was strongly considering going back to Stage 1 and stock manifold because of the driveability issues but it seems it was just how I set things up initially causing problems. You live and you learn. The best bet is really to set up as IE does. Well except on their dyno runs they run a line directly to the intake (no catch can) and one with their valve cover just vented with a filter (again no catch can). Thats fine for a couple short runs but if you actually drive the car I would highly recommend not doing either of these things. Unless you have a rag, some degreaser and a lot of time.
