Mage, no idea how pull-requests work, so here goes via Issues...

I made a brief excel sheet listing your engines (singles only) and stock equivalents. The final column is a recommendation, but please feel free to change to your own insight. The smaller ones will become cheaper, the large ones more expensive.

Thanks for the data.

Prices seemed reasonable, and have been merged into dev configs. Will be available with the next update/release.

👍 Thanks, Mage!
