MARTY FITZHENRY brought up a very good point. I believe that buying post-war stuff, from Ebay sellers, is alot safer than buying modern stuff that has electronics inside.
As BRUK posted, buying from fellow forum members can be risky. I was disappointed with a purchase I made from a forum member. I was able to salvage the item however with a bit of work.
LENNY THE LION pointed out that browsing train meets can be frustrating. Back in the day, when train meets were pretty much the only way to get a hold of post-war stuff, we were limited to meets and hobby shops that sold used trains. In those days I found train meets were the better of the two. Now days I can sit and browse thousands of items, ask questions and take my sweet loving time, to a limit, making my decision. And as Lenny pointed out, I'm not 50 any more.
