I have a Hawke 10-50x60 Sidewinder, which comes with a 4" side focus wheel, sunshade and flip up aluminium covers. The 1/4 moa turrets are exchangeable, there are 1/8 moa and 1/10 milrad available.
The glass is very clear right up to 40x, but the image softens noticeably from 40-50x. It's airgun origins are obvious with the ability to focus sharply down to 10m. Hawke also have a phone app, X-Act, that has a range of functions for all Hawke reticles and ballistic presets for calibres from .177 pellets to 12g slugs and crossbows.
I have looked through a couple of multi$k Nightforce scopes at the range and the only difference my to untrained eye on casual inspection is the clarity at the top magnification, so unless you are looking to seriously compete at +700m I can't see why one would spend more. With the 60mm objective the light gathering at dusk and dawn are excellent and the reticle has a stepless rheostat for infinite brightness adjustment.
By buying mine from a dealer in the UK (
http://www.tacticalscope.co.uk/about-us-1-w.asp) I got the scope, Leapers quick release mounts and 6 day air freight to Australia for $77 less than the Hawke webstore and $300 less than I could get it here, it also has a non-transferable lifetime warranty.
