Programmable USB Keypad for around $100?

[poorchava]

I'm looking to buy a programmable keypad to speed up my work in CAD systems. My requirements are:
-about 40-50 keys
-USB
-compatible with Win 8.1
-exchangable key graphics (eg. a transparent plastic cover under which you can put a slip of paper with a symbol)
-obtainable in EU for around $100 / €75
-multi character macros (eg. one key for 'TGM' (polygon manager) in Altium)

Most keyboards of that type are intended for POS usage, so they are very primitive (eg. PS/2 connection, only supported up to winXP, no multi-character macro capability etc). I know I could build that myself, but I don't have time for screwing around.

Not sure how this will work since it's intended for gaming, cronusmax allows you to program almost any device to map it to anything you want. They also have an API of sorts but I never used it and only know one person that has it and he uses it to play console games. But maybe you can use it to put a second keyboard and map each key.

Other than that, there are plenty of keyboards that allow you to create macros, but not with 40-50 keys.

Sounds like you want something like the X-Keys stuff, but it's not exactly within your budget: http://xkeys.com/XkeysKeyboards/index.php

There area also some gaming accessories that would certainly do everything you want, although I haven't seen any with 60 keys and you'd have to stick your own legends on.

I've actually been looking for something similar, but with more like 30 keys--I really just want a 10-key numpad, arrows, tab, del, backspace, home, end, and enter and a couple others in a left-hand friendly layout.  I'm half seriously considering rolling my own since even if I wanted to drop $200 on something like the XKeys there doesn't seem to be anything with a suitable key count for my purposes.

I looked more into the cronusmax and I guess it's only for controller emulation via other usb devices.

But I found this for $190

It doesn't have exchangeable key labels and it only has 20 keys, but they can be switched between 8 different key maps.
Other than that, it should work for you: http://www.razerzone.com/gaming-keyboards-keypads/razer-orbweaver
