That Takumi mechanical calculator looks pretty cool.
IBM made some numpad:Show Image(http://www.nextcomp.hu/pictures/image/n_ibm-numpad-usb_147_1.jpg)
Rubber domes. It's a Chicony judging by the KU-9880 designation. Those are okay to poor feel wise. Most of the Chicony keyboards I've used were very mediocre by rubber dome standards.
I have these below and enjoy them. See also this thread (http://geekhack.org/showthread.php?9112-Numeric-Keypad-Recommendations).

I have the Goldtouch too, but mine unexpectedly came with black switch... I never saw any mention of it having blacks. But I can't complain since it was only $5 nib.
anyone know if the tekgadget is plate mounted?
No, the tekgadget is PCB mounted. It's a really nice unit for the price. The extra keys (space, tab, bksp, etc) are actually pretty handy too.I didn't consider that one but now that I'm looking at it, it does look very cool ;D

A caution about Tekgadget for all Geekhack members. I paid for a KP-701 Professional Mechanical Keypad (USB,PS/2) (http://tekgadget.com/product_info.php?products_id=40) about 3 weeks ago. I never received it! I wrote to them at least 5 times to ask for the UPS tracking number or to give me a refund if that wasn't possible. They never replied my e-mails (I tried all their e-mail addresses I could find, including the one linked to their PayPal account.) I'm now working with PayPal to get my money back. It looks like their Amazon store front/webstore has closed. My experience with this company has been very disappointing. There were some features about this keypad that I liked - independent Num Lock, Cherry blues, large 0, programmable keys. But I wouldn't like to deal with a company with such poor customer service. I'm not even sure if it still exists.Ouch, guess I cant go with that model then. I really did like the extra features.
I've since bought a Kinesis Low-Force Keypad (http://www.kinesis-ergo.com/keypads.htm), which should arrive next week. It has independent Num Lock, Cherry browns, large 0, and keys that I can use when working on spreadsheets.
Damn I was really considering that one too with all those extra keys
