What's your use for the spotting scope? Backpacking only, truck hunting only, do-it-all scope, etc.
You'll be able to get a higher level compact spotter due to them being cheaper originally. I started with a vortex 50, upgraded to a Swaro ATM 65HD, went without a spotter for a few years, picked up an Ares 65, and now have a Kowa 774.
I really wanted to like the Ares 65 that everyone writes rave reviews about, but I never felt like it resolved that much better than my 12x binos in normal hunting conditions (overcast, inclement weather, low light, and mid-day mirage).
If you wanted a compact spotter and are able to accept the restricted FOV, I'd pick up a used Kowa 55 on the classifieds for $1,200.
If you want a truck/big spotter, I'd lean towards the Meopta 82 but you'll need to bump your budget to more like $1,500+.
I'd struggle to recommend a do-it-all spotter in the 65mm category that will actually be useful on top of your EL's for less than $1,500.
