I bought one of these in 2010 direct from Unicomp and have just bought a second one from keyboardco.com. There are slight differences.
The picture on the keyboardco site is of the older keyboard - there have been some changes to the bottom row of keys. Both have the same model number UB434HA.
The new one feels tighter than the old one, but this is probably due to the older one having six years of wear-in. The old one is more clacky than the new one. I'd say the old one is closer to the original but both are fine in my opinion. The enter keys on both keyboards have a higher-pitch clack than the other keys, as another reviewer pointed out.
Both keyboards are the same basic colour but the keycaps on the new one are plain grey whereas the older ones have a kind-of sparkle sheen to them. The imprints on the new keyboard are lighter (less bold) then the old one.
The main difference between them is in the bottom row of keys. On the old one, the super (windows) keys, alt and menu keys are the same size (all five are about 17mm across), being between the standard key size (12mm) and the control keys (22mm). This is as depicted in the image on the keyboardco web site.
The new one has the same sized standard keys (12mm) and control keys(22mm) but the left-hand super (windows) key is a standard 12mm key and the left Alt key is 22mm. On the right-hand side the super key is 17mm and the AltGr and Control keys are 22mm. The menu key is a standard 12mm key.
The new keyboard has horrid new-style Windows logos and a different menu symbol and the ordering of the right-hand Windows and Alt keys has been switched so that the Windows key is next to the space-bar on the newer keyboard.
The space-bars are also different lengths old=100mm vs new=114mm. The new one has a Euro symbol on the 4$ key.
Everything else is pretty-much the same: wiight, size, build quality, etc. Having used one of these for six years, I would recommend them to anyone!
