I got a late start at turkey hunting, also. Started 12 years ago at age 60. As mentioned, the Enticer pot calls are excellent and very reasonably priced. I have a number of them and Al Holbert is local to me. Give Al a call at 570-395-3279. Tell him your situation and see what he says. The nice thing about pot calls is the strikers don't cost much and each striker produces a different sound. The more different sounds you can produce, the better your chances are.
You don't have to be a great caller to kill gobblers. Some of them will come in after just a few yelps. It's the tough ones you will need the skills for. Don't over call, if they start to come in, just be quiet. Don't call any louder than you have to. Some soft purrs and clucks and scratching in the leaves works great.
I'm not very good with mouth calls. I keep one in my mouth in case I need to do a couple of clucks when they are in close to get them to stick their head up when I am ready to shoot.
I also carry a Lynch Foolproof 101 box call. It is very easy to use and sounds great. They can be found on Ebay for a reasonable price. Mine was made in the mid '70's.
