Which AR-15?

[LeJerk]

I'm looking at two Bushmasters online. One out of state, and another down near Colorado Springs. Which should I go with? The 20" barrel "predator" model is more what I was looking for to save weight and barrel length. It's $900 and almost new. The 24" "varminter" model is the out of state one for $1200, but it has a nice scope and it all set up with the stock I like too. I think I'm going to go with the one for $1200 that is already set up how I want it. I know doing the FFL thing may be a pain and some extra money, but after I get the one for $900, I would have to put a lot more than the difference in price into it to make it the same thing. What do you guys think?
