I have decided on these for my first mid tier IEMs. Right now the best deal I can find is for $150 including shipping, but I've heard it often can be found for cheaper.  I'm interested in the Onyx Black version only (product # 010-045).  What's the cheapest you guys have seen them/bought them...

Just looking into buying a pair of buds that I can use when I walk around, workout, video chat, etc.  Sort of an all-purpose set that has decent durability.  Preferably under $100 but if justified can go up to $150, maybe higher.  I'm by no means an audophile, but I do care for clear sounding...
