I bought maybe 30-40 IN-14s a while back when they were going for a used price of $2-2.5 per tube after including shipping.
I finally used up most of my stash building clocks for family and friends and I wanted to get a few more, but wow the prices have ballooned. The exact ebay listing I used for a lot of 6 a few years ago went from $20 to $100 from the same seller!
I haven't been in the buying business often enough to know if this is a price wave that will eventually subside, or because of rising popularity and limited stock the prices will only go up.
I'm wondering what should be a fair price for IN-14s now? I'm seeing maybe $15 per used tube? Am I just looking at the wrong places or is eBay still an ok place?
