Both the PTS 51 and the nexstar are over hyped, overpriced and overloaded with Gimickry that serves no real purpose but to lengthen the learning curve.

Neither one or any other for that matter is going to alter the fact that the shortest possible learning curve for 'you' will hinge on wether or not you find a good mentor/instructor.

Both can be used successfully with a mentor but neither are the "BEST" trainer of which there are number that fits that description a lot more faithfully.

So go ahead and buy either if you just cannot wait but just don,t make the assumption you have picked the best. The best can only be worked out by you and your future mentor/instructor together.
