Slide rules still commercially available?

I made her a quick and dirty iPad rendition in Numbers (would have been Lotus, but she doesn't use an LX), and then went hunting around and found they're still commercially available!

Are there any other companies still commercially producing some form of slide rules/cardboard "computers"? I'm guessing they'd all be pretty special-purpose, much like the EZ Grader products.

Last year I bought a Faber-Castell 2/83N direct from Germany -- brand new, top-of-the-line with a huge number of scales on it. It ran about 80 euros as I recall, including shipment to Australia. My brother-in-law liked it so much that I bought him one for Christmas...
