Well, I am just getting back into duck hunting after being absent for about 15 years. I have not invested in a high-end call simply because I have a nasty habit of losing stuff. A couple of years ago, I bought a Big River double reed, and didn't like it at all. The pitch was too high, and it sounded "off". Since that time, I have tried the Knight & Hale calls, the Primos, and a few others, and although the sound was better, they were not perfect. The test for each was a day that a lent out a couple of calls to some buddies on the other side of the slough.... it's amazing how bad some calls sound (although this was probably also due to the callers).
Anyway, last year, I decided to do some more shopping. I hit the sporting goods stores and got my catalogs out. I was ready to order a Rich 'N Tone when a buddy suggested I try a Woods double reed call. A local store stocked it, I bought one, and I am impressed by the sound. Better yet, it only cost $25. I used it last season, and it performed very well. I would recommend it for a person that wants an economical call.
