Oh man, this is an awesome story. I can just imagine this pile of keyboards in a Turkish Bazaar, sitting next to the spice dealer. Awesome, simply awesome. I love Turkey, btw. And since you're Turkish, I don't have to tell you how to negotiate, because it's part of you culture. So my advice is to go back and try to buy the whole lot, but don't let on that you think they might be valuable, and try to get the seller down to like $1 per keyboard. Then take them home, clean them up, and resell them to us. If you feel nervous about recouping your investment, try to get as many pictures of the keyboards as possible, and post them here. There are enough experts here who will tell you exactly what's in that pile of keyboards, if you give them photo's with enough detail. So make sure you have lots of good light. And take a camera better than a cell phone. Be forewarned that you may have a pile of crappy rubber-domed keyboard too, so be careful.
I think he has no idea what they worth...To him, they are just old keyboards

I guess you were in Turkey and visit the good old famous Grand Bazaar?

Imagine a shop in the bazaar with a mountain of old keyboards, some old apple computers, commodores, ataris.. and a little old fella smoking his cigarette and smiling to you and offers you a tea..

And let me tell you something more interesting, i have never met any Turkish person with any real knowledge about keyboards, or how worthy they are..I'm sure there are only 100 people in the whole country knows the difference between rubber and mechanical

I think i will bring my Filco key cap remover with me next week..i can't go before cause it's a bazaar open only in Sundays. Sure there were some rubber keyboards, they were also $5, same as model M's...But that is a good idea, i can tell the guy that i'm going to use them in an orphanage with lots of old computers, and i'll ask him to lower the price..like $3-4 each..By the way, i typed bunch of those keyboards, like 7-8 of them and they were mechanical..not rubber..there was a little Cherry, clicky..and it was so cute

and old. Maybe i should buy them all...
