I just bought a Boyer MkIV kit, but didn't get it for $150. Bought it from somebody in the same state, not all the close though. I suppose I should have looked harder for a better price.
I agree about the price of the basic EI products being reasonable. Try building a Pro Touring 60's Muscle car if you want to spend some money.
Anyway, my intention is to test the hype surrounding the theoretical improvement difference between the MkIII and MkIV box. I'm hoping it's not just a different sticker on the box, cuz I'm real tired of that kickback crap on my pseudo battery less setup. I got the Boyer because it is the least amount of rework. All I need to do is swap black boxes.
The SureFire Pazon looks like the same thing Boyer is selling to me. I'm sure it's magical, but that's what I see when I look at it.
Good luck. I'm sure the Pazon will do the job.
