+1 to
krypt0nite's suggestion for a mechanical keyboard.
The Steelseries 6Gv2 I have is the first mechancial KB that I've ever purchased. I previously owned a Logitech G510. The G510 was a decent keyboard and worked well for me. But, I later moved to the 6Gv2 and absolutely love it...the build quality is superb and the keys feel really good. There's no doubt in my mind, this is a keyboard that's built to last.
Unfortunately, there's not too many back-lit mechanical boards out there. Off the top of my head, I can only think of Deck keyboards or the new Razer mechanical keyboard are back-lit.
