Super Job !!
I could have made a helluva lotta use from this when I got back into The Hobby after a long lay-off . I did find something like it later but it had no search engine.
I created a similar spreadsheet on engines when I was trying to sort out all the "new" stuff offered. Shame I lost the back-up disc. Of course I discovered this after having to wipe the drive on my PC.
But I had maybe 50-60 engines on it. Nothing like this.
