Anybody use Westone in-ear monitors?

One of our members has asked for advice on purchasing in-ear monitors. It's such a subjective issue, that I wanted to throw the question to all of our readers. What in-ear monitors are you using? Like them? Would you buy them again when it's time to replace them?

Specifically, anybody use Westone in-ear monitors? Our member found a great deal on them, but wonders (as I do) if they're inexpensive or if they're crummy. Your thoughts?
