The Huina works pretty well...I have customised mine a lot...added a base plate for extra weight..used code 100 HO model rail segments on every second grouser plate for better traction , painted the undercarriage and tracks , blade and guard rails and made CAT emblems by hand...couple of other mods... probably cost me $20 max....runs and pushes much better and looks the part now too... that's the beauty of Huina...very mod friendly...these of yours are great...like them both...
