While I wouldn't argue for a second against them being worth having and making life very easy, I'm not sure I agree that they're cheap.
Cheap is relative. Keep in mind that these are nothing more than ordinary machine screws with larger, knurled heads and probably cost less than ten cents each to manufacture ... so paying around thirty bucks for a set isn't my idea of cheap.
