I do a lot of long range shooting and hunting and have used a lot of rangefinders (Bushnell, Leica, Gunworks, Vortex, Sig, Terrapin, Vectronics, etc), and I would say the best bang for your buck would be the Sig Kilo 2200MR. It will range out to 3,000 yards in perfect conditions (I've hit 3,340 with mine once), but will regularly range out to a mile with ease. It also has a fast scan mode and angle range compensation. You can get them for around $400.
Unless you need a rangefinder that will tie in all of your ballistic data and output your drops in MRAD/MOA, this is the best bang for the buck by far, in my opinion.
