Good: high quality, often referred to as the best precision equipment, and often lasts many years. If parts go bad can often replace just that part.
Bad: It costs more than if you bought a "normal" stick every year for 5 years. IMO has too few buttons (too many buttons-on-hats and not enough stand-alone) <- but this is just my opinion. Some parts can go bad, before the full stick.
It's up to you if you want to spend that much $$$. If CH made a setup like Saitek, but with CH quality, I'd love that. IMO Saitek doesn't have the quality/longevity, and CH doesn't have the functionality/ergonomics of the X52-type system. (this said just from observing the setups).
