Idle Timing/Ignition Analyzer 1993 Johnson

Hey there, I am going through the engine on a Nitro I just bought a couple weeks ago. It's got a 1993 Johnson 150 on it. I am to the point where I want to make the Idle Adjustment, and for those familiar you know I need the Ignition Analyzer P/N 434017.

1. My first basic question is, anyone out there got one of these and use it etc......?

2. Anyone got one that they don't use and want to sell?

3. Anyone figured out a way around having to buy this particular meter and are using a replacement that would cost a lot less?

4. Anyone out there live in the Northern Kentucky (Cincinnati), or near Barren River Lake that would either want to share the one they got (Rent it to me) or would want to go in on buying one. The more the better. This tool would work on many models and I have a shop manual that list's all these models:
