Skcheng is awesome. He refurbed and modified my favorite Model F with dental tools. At dentist rates, I estimate he put $10k labor into it. It's tempting to encase it in lucite but I keep using it.
EDIT: FWIW They had either 100 @ $30 each or 300 @ $10 each - industrial space saving tops, I can't recall which. A few people on here bought some, as well as their supply of IBM logo stickers in black. Then Webwit bought out their stock.
