A new GSG-5; looks like an EBR but only costs $500.
A Remington PSS; an EBR (Evil Bolt Rifle) but with a decent scope you'll use the entire $1200 or more, but you'll be able to reach out and touch someone
PS90 at Tanner's. They were $1150
PTR-91 - in the $700-$1000 range depending on model, just don't plan on reloading the brass.
FAL - $700 - $1200 depending on make and model. The go to gun in the rest of the non-combloc world
AK - $350-$1200 depening on make and model. Everybody should have at least one
M1A - Might be able to find a used one for $1000-$1200
I'm sure there are a few I missed.
