does anyone have a lucky duck electronic predator call?

[buckhound]

I am reading the sound is better than fox pro the riot the one I was looking at comes with 50 sounds but looks like you have to buy additional at $8 or $100 ? for a bundle. so just curious if anyone has one and what there experience is.  the fox pro hammer jack  even though they are more to start you get more calls 100 included and get 111 calls free to add later.
