I like the AEK much better than the AEK2, those dampened switches are kind of weird to me.
I don't currently have an AEK, and if I went to the trouble to mess with each switch individually, I would probably not be willing to sell it.
If anybody wants to try an AEK2 cheap, I have one that I will sell that has not been cleaned or tested for $10 + shipping.
It is not bad overall, all the keys seem to click properly, but I sold my ADB-to-USB adapter along with the AEK.
