Best leggings/tights for running?

What are some of your best brands for running tights/leggings?

Most of the brands I've found (Nike, Under Armor, Atleta) fit me all wrong. They're either well fitting in the thigh/butt area but then falling down around the waist, or super tight around the waist. Either way I'm fiddling the entire time with the waist band when I should be running and it's quite difficult to run if you spend the whole time trying to pull up your pants!

The only brand I've found that I absolutely love is Lululemon, but the issue is that their running leggings can cost anywhere from $85-100+!!!!

I would say I'm more hourglass/pear shaped and I definitely have a larger butt, so has anyone found any running tights/leggings that they don't have to hold up the entire run!? (and are cheaper than Lulu)

Thanks in advance :)
