   BS! He's the one that shipped it without the pods. You're entitled to
all of your money back! If he wants it back, then he should pay for the
return shipping. Furthermore the missing pods, leads and grabbers are worth
considerably more than $50! In fact, he has it backwards. The LA without
the accessories MIGHT be worth $50. The accessories are worth $200!

   I'm sure they're special cables. If they didn't need to be then HP would
have used IDC cables. I have NEVER seen a LA that used IDC cables and I
have a LOT of them. (Gould, Dolch, HP, Tektronix, Paratronics, etc, etc)
