I was just cruising Taobao and I found this keyboard:

I recognized a few of the keycaps because I found 2 of these boards at a local recycling place. There's another seller that has done the same thing with these boards.
Originally these boards had a ton of custom keycaps. All the F keys, as well as the cluster above the numpad and even the arrow keys were all custom pad printed caps for what looked like a bank to me. You can tell that some of them are still there...the numpad caps are all worn down and the enter and tab keys are a different font.
The keyboards has some very cool caps orignally as well..there was a Purple cap that says calculator. I had one of these and I sold it to Ascaii. The ALT and CTRL keys were green and blue (shift keys were normal). Someone obviously has removed most of the custom caps and replaced them with lasered one...and it looks terrible.
The question is how do these boards make it to China? Recyclers just sell it in bulk or something? If you look closely, there is a tag on the back that says these came from Spokane, Washington...same place mine came from.
