Ok let's start with this, what do you want out of this rifle? Basic calling rifle, unless you're like me and want to have a bad [beeep] calling rifle you could do it for a grand. How far do you walk? If you don't walk a whole lot maybe weight isn't a huge issue, sometimes cutting weight can cost more (not always). So you want a complete upper and lower? First off, go to JoeBobOutfitters a PM sponsor, check out some of their stuff, the easiest way to find out what you want is to look. Midway is also another good place to look. Like Plant.One said though, basically all lowers are the same and you won't see a difference if you pay a lot more. Your upper is going to depend completely on what you want out of your gun.
Maybe you should look at complete ARs? PTG makes good guns, also a PM sponsor. Ritch makes awesome uppers, really good uppers. Many will vouche for him. Have you looked at the *gulp* Remington AR, or maybe the Mossberg AR? Lots of people like these guns. Like I said earlier, there is toooooooo many options to actually go through them all, my first AR was a S&W M&P Sport II, it's more tactical than hunting styled, but I take it calling without regret. It was only like.... $550 I think?
Just look around, Budsgunshop is a good place to look also.
