sierra trading post has a couple of pairs of shebeest bottoms on crazy sale right now:

-Tech tights for $36
-SSS shorts for $32
-Elite Distance 2 shorts for $39

Plus if you get their emails, there's a $20 off & free shipping for orders over $60 right now.

I highly recommend the Tech Tights, I have several pairs. They're very well cut, have supportive fabric and personally I'm a big fan of the Shelastic chamois.
