OK, with so many takers, and just 1 hot tip, I am just gonna post it here, and let fate decide..
My container is still 2 months away, but in the meantime I found another seller.
He's a Greek chap in Germany, and the type of guy with the most fragile of ego's. Paranoid, basically.
He's got a bunch of NOS parts at completely delusional pricing. Do not even speak about other parts. Do not complicate the conversation, payment of shipping suggestions in any way, or he will slam the door shut.
Never dealt with anyone that needed that much handling.. I walked, after 2 weeks of emails, because I already have a "238" and it just wasn't worth the drama for me.
Find a credible way to explain how come you know about his existence. He was on ebay and/or ebay Klein 2 months ago, offering another part.
He's got the xxxx238 in NOS for 140 euros. It's the only good thing there, and he didn't know the real value. Everything else he sells is madness.
You may PM or email me. The first caller gets the email address. No seconds, because if this guy gets 2 mails in a week, he will reach for the Lithium right away. He only speaks Greek and broken German, btw. Good luck with that, haha!
