I got a Cooler Master Quickfire Rapid (Rapid is the most "barebones" version of the keyboard; other versions: TK = has a numpad; Stealth = keys printed on the side; Pro = has backlighting) with Cherry MX Blue switches (my favorites for typing; if you're interested I recommend reading up on the switches: http://www.keyboardco.com/blog/index.php/2012/12/an-introduc...)
Before that I had been using a bluetooth Apple keyboard for years; but I felt that I typed sloppily on it and that it hurt my wrists. Changing to mechanical has been great for that; if you're not a touch typist, it'll definitely encourage you to lean that way.
And finally, the amazing things with Cherry MX caps is that you can buy custom caps online (or 3D print your own!). So now my keyboard looks like this, which I find lovely :) http://i.imgur.com/j1jZN1a.jpg
Finally, if you're working in tech, you probably have a crazy hacker friend who owns a Happy Hacking Keyboard and talks about it all the time. Those use Topre switches, which have a different feel than Cherry MX, and are super expensive (300$ when you include shipping and tax); but damn, they look good, are super portable, and quite comfortable (available in black/white and printed/non printed and ansi/mac layouts). However, they're really meant for UNIX usage- if you don't spend 90%+ of your time in terminal applications of some form, then it's not for you. They have a mac layout that makes things a bit easier if you use a mac, but it's still very much hacker oriented.
Also, avoid the Lite version- while it is much cheaper, it uses rubber dome switches (the kind of switches in traditional cheap keyboards) and is just not worth it.
The hacker keyboard rabbit hole is a deep one (for example, there are people who swear only by Japanese keyboards because they have a smaller space bar and thus have more meta keys/are more compact). It may seem a little superficial and silly, but hey- you're spending dozens of hours a week on your keyboard. Having something that you feel is comfortable and looks nice can make your computing experience significantly better :)
