I have started buying stuff out of Japan and getting some real bargains to boot although recaro's for some reason are still stupidly expensive as freight and fees do add up on top of sale price which is reasonable anyway I had a quick look for you, found about 2000 sets of recaros, as for your fishnets there were about 100 sets. Average price was about $300 a pair, Ideally would buy with rails as well also be aware that air-bags will be removed prior to shipping as a legal requirement. I have use google and microsoft translate to make sense of the Japanese auction websites which can be a challenge as they translation can be a bit hard to understand fortunately most auctions include good pictures and detail damage.
as an example for you $130 a pair
or if you are planning oon recovering them how about $11 dollors each
if leather and money are what you want and have $1950
now the bad news those prices do not include freight and fees
Now to save money and make it easy on myself I have used and recommend (highly) Jesse Streeter

a drift racer living in Japan, here how it works
You find an item you want either from Yahoo auctions or some other auction site or from a manufacturer, he has discount deals with many suppliers
Email him with details on item
He emails you with buy price in AU $ to be paid into his Au bank account AND a estimate of freight and fees that will need to be paid prior to postage to you.
He then buys item for you and has it delivered to his warehouse where tires will be removed from wheels or air-bags from seats etc and item is repackaged ready for freight
He emails you will final amount to be paid into his account for freight and fees. and on receipt of money sends items to you
As an example I paid $805 for a set of Volk Racing forged wheels at auction
then two weeks later I paid $500 for freight and fees
Six weeks later delivered to my door they arrived total cost $1305.00 verses normal retail in Au of $3200
Anyways hope that helps, I had another look before posting this and found a traditional old school looking stet for $216
