When I reserved my sample, George was very helpful and my (first) impression was very positive. He send me some pictures of what may be the traditional version and what may be the modern version. He also mentioned to me a price of about $700. It's certainly not cheap, but I still remember the Key PRR J1. I believe that one was (when it came out) about $800. Luckily it still is a great engine, which these days is very hard to get. As a penny fan a L1 is a must (well at least for me)
