Will you call in yotes with the Preymaster? Yes, my buddy does. Will it seem as robust and full featured as the Foxpro? Maybe. Can you get all you want soundwise on the Preymater? Probably not. Why does someone own Craftsman tools versus Kodiak brand at Lowes? Or Snap-On over MAC? They are tools made by tool companies to appeal to a certain customer. And each of these companies make tools to do the same thing, yet they are different in terms of company support, warranty, price, reputation, etc.
You need to decide what you want/expect and then determine what your budget can afford you. Just make sure you factor in all things. I personally just bought my third Foxpro (FX5, then Fury, now CS24) and I am pleased. They are a great company. Before that it was a Burnham Brothers (which called in a LOT of dogs for the three years I used it) and then a homejob electronic with mp3 player before the BB! Each of these worked just fine!
