You can get HL wholesale very cheap, only have to order in cases of 4. I used to get offers all the time, they'll even send a sample or two. Off the top of my head, I think the most expensive was the Tiger I with metal gears and tracks at $31. Problem is shipping. The only cost effective way to get them here is in containers, otherwise they're going EMS.

EMS on my JS-2 from Japan was $94. A metal tracked Tiger should be similar weight, so that brings it up to US retail. I got one quote on surface for a case, I think it was in the $150s.
