To elaborate: The 1/2" deep panel jacks look really cool, and they're easy to wire up, but when one zoinks... it's just zoinked. You can stare at it, yell at it, cuss and such, but you certainly better keep a spare around, cause there's no hope. On the regular (7/8") open jack, they do wear out, it's a good idea to keep a sack of them around, but even in their death throes you usually can bend the prong back with your finger to finish one more gig.
