Since you don't want to get a 120+ HZ monitor (which are really nice by the way) then i would suggest the ASUS VE248H. Its a great monitor and can provide an amazing and sharp look. Here is a link. http://goo.gl/zsq55k
Hopefully you find the right monitor for you and I hope you consider ASUS VE248H . Good luck on your build.
By the way, the prices vary alot some may be more expensive and less expensive. However there are some out there that fit your price range.
