Thermaltake Meka G1.
Doesn't get enough recognition. This thing's built like a tank.
I've heard great things about that keyboard too. Sadly, it wasn't what I wanted in terms of the full package of features and specs.
With some preferences toward specs/features, the market is saturated like crazy with quality mech boards. With other preferences, there is almost zero market.
For example, you cannot even find anyone offering full sets of Cherry MX keycaps that offer solid color except for translucent letters. You can find all sorts of keycap sets, and some translucent ones, but none where the light only shines through the letter.
I was really not impressed with the build quality of the razer keyboards I purchased. I really like the looks of the new corsair keyboards, but reviews have stated that quite a few of the buttons of them are not mechanical.
While I'd agree that most Razer products have questionable build quality, the Razer BWU Stealth is a tremendous product thus far. It actually feels like a huge upgrade over the regular BWU.
I still need to really discover the truth come a year or so from now, but based on owning a multitude of previous Razer products, I really believe this board will stand the test of time.
Not saying some boards of the same model won't have manufacturing faults, but the baseline product seems to have a growing fanbase as more people get their hands on them... especially if they had the stock BW/BWU to make the comparison. There has even been some praise on geekhack, which is full of mech board lovers. Razer is fighting an uphill battle though with the mech enthusiasts, because they've got something of a black eye (and that is understandable). But the few who are daring enough to try the board, ignoring past experiences or simply taking that gamble... seem to be coming away happy.
I'm no Razer fanboy or anything, hell, I've got more Logitech products than anything. The KB is the only remaining Razer product in use, as I recently got the Logitech G700 mouse and I'm not turning back to the Razer mice.
But I'm prone to really throw support toward products I think deserve them, even when the company has ultimately disappointed me more often than not.
