Hey, I'm new to mechanical keyboards as well and I recently went through the process of choosing a 60% board. I basically "live" in a *nix terminal and play no games. This was my short-list:
HHKB Pro 2
Ducky Mini
Vortex Pok3r
Ultimate Hacking Keyboard
KBParadise V60
I ultimately chose the Pok3r ("poker 3") with HHKB Pro 2 and Ducky Mini as runners up.
First, I decided against the KBParadise V60 because it felt more of a "value" option and getting great value wasn't my objective. I also eliminated the Ultimate Hacking Keyboard simply because it wasn't out yet.
The second place runner up for me was the HHKB Pro 2. This is possibly the best reviewed 60% board I've seen. However I'm just not a fan of the key placement. First, I get the whole [Del] and [Control] thing, but it's not for me. I'm so used to the [Control] key being in the bottom left corner for shortcuts that it just isn't that attractive to have it above the left [Shift], even if that was the original way it was done. I also find the [FN] key on this board way to the right of the right [Shift] too awkward to reach, especially in combination with other keys under my right hand. There are other things (moving the tilde) which are just very non-standard in today's world. It's just not natural to me. But again, this is all personal preference. The vast majority of people have a different opinion than me.
The first place runner up was the Ducky Mini. This is a beefy board with a great layout and a great configuration. It also lights up with all types of cool effects if you're into that. It also has mouse-movement built into the keyboard which is interesting. This just seems like a great work-horse board that was well thought out.
My winner was the Vortex Pok3r. The thing I love most about this board is the layout of the secondary function keys (the keys you have to move your hands for on full keyboards). For example, the arrow keys are placed under I, J, K, L which is sort of the opposite of W, A, S, D. (It's also not like Vim.) While this seems weird at first glace, once you realize you can flip switch 3 on the board and re-map [Caps Lock] to [FN] it really makes sense. On the Pok3r, all the secondary function keys are on the right side. When you press down the remapped [Caps Lock] (which is re-mapped to [FN]), with your left hand, you have access to all the secondary function keys at or near the home-row of your right hand. I picked up this system in about 5 minutes and it feels extremely natural. It's as natural as using [Shift] to capitalize a letter. Other than the great key layout, the Pok3r had the most advanced ability I've seen to program macros (the functionality is fully contained in the keyboard so no software required on your system for macros). I've only started messing with the macro programming but so far so good. It also comes standard with nice PBT keycaps (unless you want a LED-lit version), and it has a really heavy standard case which other reviews have said is an expensive upgrade on other boards.
Anyway, my advice is to skim through the PDF manuals (which are all online) and take a close look at how things are laid out. That can give you a good idea of what it would be like to use different products.
Again, I'm new to the world of mechanical keyboards so please take my advice with a grain of salt. There are much more knowledgeable people here and I may be wrong on some things. Regardless, I hope this gives you some other options to consider.
