First off, I wasn't asking for anyone to give them to me. I was just looking for a discounted price. Sorry if I wasn't clear.
Every week, on eBay you can buy volcano buttons for about $10 each. You can also buy them new from arcade vendors for $19 each ($22 with bezels). I just bought some volcano buttons on eBay ($10 each with cones). The seller claimed they were in good condition, but they all needed their LED's replaced and one of the cones had a cigarette burn. I received 2 kinds of volcano switches. On one switch the LED is relatively easy to remove (just unscrew and solder). On the other kind, I had to drill out the rivets and then melt the plastic to remove the LED contacts. Next I had to solder the contact to the LED and melt the plastic again to reinsert the contacts. You have to be careful when melting the plastic not to damage the components of the microswitch. I'm sure anyone here could do it, but it is a hassle for a $10 switch. Still, you end up with volcano buttons that are brighter than the originals.
