eBay and Craigslist finds

Any idea where I will have better chance finding a 2A than ebay? I have been looking for a 90mm - 100mm for months and haven't see a single one for sale?!?

Besides the Cinelli 1A stem, there are also dedicated track / sprinters stems, named 2A and 3A. 1A has an angle of 73°, the 2A has a sharper angle of 65°, 3A even more extreme, 58°.
