Shipping is going to be a killer for anything overseas. This is probably one of those items in which you have to bite the bullet and go ahead & pay.
However & just throwing it out there, if 2 or more guys could get together & come to a firm agreement, then the cost could be reduced. Two of them are about $18.35T each from Megazip. Four would be about $15.30T each if you include the additional cost of re-shipping the extras by USPS priority mail small flat rate shipping. I'm assuming the shipping cost from overseas would be the same for 2, 4 or more of those little parts.
