Hey Dan,
+1 on the Yamaha HS80M's. I just traded in my KRK V8's with a 12" sub for a pair of these and am not looking back (the krk's originally cost almost $2000) and my only regret is that I cannot go back in time and pick the Yamaha's over the KRK's on my original purchase.
The HS80M's are going for $249
a pair EACH (sorry) from a few vendors on Amazon and Guitar Center was more than happy to price match down to $240 each from their price of $349.
I'm still finding my sweet spot with them so I haven't any mix I'm willing to post yet, but what I've done so far translates much better, with a lot less EQ work, than anything I did with the KRK's.
Don't get me wrong, the KRK's sounded great. And that was the problem, for mixing, you don't want monitors that sound great but monitors that sound accurate. It is up to you to make your mix sound great.
One other thing is that the Yammies have got plenty of volume to tick off your condo-neighbor's if you wanted to. I usually mix at an SPL of 85db and had to set the monitor trims to a little less than half at 11:00 to get to that level.
Just my nickel's worth of insight.
