That's why when I order from TH, I always thow in extra servo repair kits. Just to have a bunch of them laying around.
It would be nice if i can just get one perticular gear...i don't really need the entire kit.

the ceramic filter is either a capacitor or an inductor.
capacitors cost manufactures .08 on the average.lol
the casing probably costed them $.05 on the average.

Anyway...they're not going to be making out like bandits.
probably loose money, becuase it probably took someone more than an hour to inspect all you're stuff.
Someone else to punch in the informations of your order.
Someone else to un wrap your order.
Someone else to type you an e-mail
Someone else to stock your stuff on the shelf until you make up your mind.
