An engine just like that almost got me into largescale a bit earlier than actually happened. I believe it was priced at around $3000 when it first came out. A real beauty and much better in person than in a photo. It was 1:24 scale. I almost bit but I was heavily into On3 at the time and chickened out.
As you say it's nice that some of the great talent around here can build one from scratch just as nice thanks to Fletch and friends.
