Actually I've been trying to find a decent kit/ARF that I can recommend to people who buy my pulsejet engines.
Every time I convert an ARF to pulsejet it seems they stop making them so I have to look elsewhere. I was almost at the point of having a kit/ARF specially made.
Most people don't want to scratch-build, they want to buy an engine and buy an kit (or preferably an ARF). Maybe the Wonder would be a good option.
