Butch,
I am very happy with the pair of PRR DGLE A units I purchased. They are drop dead gorgeous. They operate extremely well, beginning with a less-than-walking speed. They are fabulously decorated and have only two very, very minor detail flaws.
They pull very well. I may add some weight to them as I intend to utilize them on very long trains. The QSI Titan Magnum decoder is spectacular in its sound sets. Admittedly I have not made many adjustments to CVs yet. The top speed is about 45-50 smph, which is satisfactory. It would be great if they went upwards up 70smph, but at this point I am not going to change the ratios in the drivetrain.
In short, they ARE great models for the money.
