Lots of good choices out there. Everyone has their favorites. It be hard to lead you in any one direction.
Look up such call manufacturers as, zink, foiles, tim grounds, sean mann, buck gardner, lynch mob, Gk calls, and the list can continue. Right now I am using a Shawn Stahl SS-1 and SS-2. I like them both pretty well. I've also tried a few Zink calls and am pleased with them. And of course I've used a few cheap no name calls as well. I would recommend browsing the calling forums. There is a ton of info and likely all your questions have already been answered some where.
Most importantly, as every one hear says, go to a store and try them out if you can. No one can recommend what the right call for you is going to be.
Good luck with your quest!!!
