I had a cheap cheap HS call but it was a good place to start. When I saw the J-frame in the local Wal-mart, last year I called RNT and ask them about it. (They were really really nice and very helpfull. YOU SHOULD GIVE THEM A CALL AND TALK WITH THEM ABOUT THE CALLS).
The J-farme is based on the Org. Sound is going to be a little different because it is polly and not wood or arc. Polly is a lot cheaper to use, and it still blows wet and cold. Same reed though.
It is loud which is ok for me I will be in some open fileds. To off set it I am going to get a Quackhead timber. I love the price under 25.00 and I easy to find at any Wal-Mart. They are really easy to blow and I like the sound I get for the single reed, and they now also have it in double reed.
I went cheaper because I am new to waterfowling and needed to get other things like dekes, waders, new gun, a dog, boat would benice also but down the road. Still working on the dog, wife is not sure why I need to spend that much for a dog. (She didn't have pets growing up so was never really a thought to her. $600.00 for a gun is ok $300.00 for a dog and she almost passed out.)
If you can, go and hear the differ. and see if the price is worth it to you. I just took a change and went with a name. I though RNT would not put out crap and I fell they didn't .
