Hello everyone, I am considering purchasing the Reppo Southern Pacific GP20. I noticed that it is a Pro Series locomotive, and the reviews are fantastic. I would like to know from those who already have it, how is the performance? Is it less intensive to run than say, Searchlight Simulation's AC4400CW? I can run Smokebox's FEF-3 with zero issues, but I am a bit leery purchase it since it is such an advanced model. Also, how realistic is it? It certainly seems fantastic, and it looks amazing. I've heard some great things about Reppo and would love to see what you all think. Thanks for the help and God bless!
