RE: Low Budget Call
Check out Tony Tebbes custom calls and Carver Predator Calls. I LOVE both, and their production series calls are usually $17 or less shipped. Anyone can afford that, and they sound great. I am almost to the point that I like hand calls MUCH better than my varmint al style ecaller. You can control what sound you are putting out and mix it up alot.
I bought a minaska amp instead of radio shack, it gets MUCH louder and crisper sounding as well. Not sure if they make them anymore, bought mine used for like 30 bucks. Uses an 8AA battery pack, and lasts several days on it. Use rechargeables and it has a charger port to charge them, no replacing batteries.
I use my ecaller more for crows and hand calls more for predators.
