My personal experience with the rear derailleurs (Prestige and Criterium) has been pretty good - and though I'm a big Suntour fan, I think Simplex performs quite well.
That being said, I think their Delrin FD's are POC's.
I've seen literally hundreds of Simplex RDs in the past two years at the bike shop, and I think I've only seen one with a broken body. The pulleys, of course, do chip and break; but when they're complete the work very nicely. I've never tried to replace them, but surely there's another brand with tougher plastic that would fit and work.
