? about electronic game calls

[billy ahring]

I'm thinking of buying an electronic game call and am looking at the Foxpro zr-2 and the Johnny Stewart preymaster. Was wondering if anyone here has any experience with either of these units and what are your likes and dislikes of each one. The foxpro is 100 bucks or so more than the johnny stewart call. As a sidenote I have one of the old style Johnny Stewart cassette calls but the battery will no longer charge so it is kinda dead in the water. Does Stewart offer new batteries? Opened it up and it is hard wired together so I don't know if they offer replacements or not. My one complaint about that system is that it is rather heavy and is a lot to lug around when going from calling stand to stand.

Thanks,
Billy
