Dude, its up to you, but the reason you may STILL be trying to sell an old 3.5" Atari floppy drive after nearly a year of trying is, like the poster above said; its just not that rare. You can basically buy one of those with a free working 520STFM attached to it for that price!
Thanks for the information. I'll think about it. With direct sales, I am ready to make a big discount; when selling on ebay I have big taxes. To equalize with the selling price on the forum there is not profitable.
