Brian,
Sorry to hear that you don't like the Power Machine. I really like mine, there just hasn't been enough oil lately to be able to use it. If you are looking to fill the medium/heavy slot in the arsenal, how about the Inertia? I have mine at 1000 Abralon and a "control" drill on it (see profile) and it works great for me. I've read that it is very adaptable to surface changes, plus it will give you a different look than your Equation. You also don't have anything in the heavy oil slot. For that I would recommend the Dyno-Thane Threshold. I just picked one up and that ball is a BEAST. If you have any other questions, PM me.
