Jason - I think you've forgotten about all the 280ZXs bought to break and beyond that, what 's wrong with someone hard-grafting* to turn a bit of profit to help get his own car back on the road AND help others with parts : noone's holding a gun to anyones' head to buy.
*the case here : I drove 300miles in a round trip to get these, removed one and the gearbox from the car and spent 2x days dismantling - how much do you earn at work in 3days ? I think that you should drop all your reactions here and on FB which appear to stem from some personal prejudice towards more abetted by a mutual aquaintance. You want to burry the hatchet - I'll dig the home and we can be friends again.
For information, both cranks and gearbox sold and strong interest on one block - the price is right ! Also, my JW stub axels sold, probably because I supplied them with OEM Subaru seals and cover gasket. Poeple want a whole package with less to do, just like the cranks.
Other cranks are here, I consider mine reasonably priced :

Jon - Dave R sells a kit - this is what he told me : $6200 Pistons, rods, billet crank, rod and main bearings, MLS head gasket.
