IODD makes some. I had the older HDD version that stopped working after it got dropped, so now I use this one:

The olde ones are nice. Not sure about the newer ones. I have two T420s and one T430. The 420 was the last of the chicklet keys I think. Can swap CPU/RAM as well. The 430 has the CPU soldered in like most major brand laptops do meow.
