I would not overlook the foxpro. Yes, it cost more but it is really nice and effective unit. I think you get what you pay for. I have never used a western rivers call so I cannot comment on them. I do know that Foxpro has the best costumer service of any product that I have ever purchased. Before you buy a caller do what I did. Call Mike Dillion at Foxpro and ask him why you should buy a foxpro. www.gofoxpro.com This guy fell in love with the sweet bunny blues of a foxpro.
