Predator caller's

Just got a nice check from my employer for my retirement, so I'm looking to purchase an electric caller. I hunt in Southern Indiana, lots of woods,thickets, and ravines along creeks. No open areas like out west.. most my shots will be close in out to 100 yards. Any suggestions?

check the laws carefully b4 you buy here in KY you cannot use an electric caller for turkeys and some other's
