I received my Quick Fire TK, with Browns, from PCHome (Taiwan), yesterday. Although the photos of the keyboard showed English only keycaps, and there was no opportunity to select an English or Chinese keyboard, the one I received was the Chinese version. Actually the two versions are the same except that the Chinese version's keycaps are English/Chinese ones. At first, I was quite surprised and a little disappointed, but now I like it's uniqueness.
With respect to a "see through" paint job, I can see only a faint glow on the back of the F1-F4 keycaps, and then only when the backighting is at the mid to maximum level. There is no other glowing on the front, back, or sides of any other keycaps. Actually, the backlighting of the board is the best of all the backlit boards that I own (1 Blackwidow Ultimate, 1 Shine I, 2 KeyCool 87s, 1 Pure, and 1 Race). Really sharp/crisp, and very even, with no bleeding. Took me a while to figure out how to use the backlighting, and to figure out that you can permanently turn on or off the Function key by holding it down for a few seconds (a very convenient function). The browns are almost as smooth as my Filco browns (have 3), but feel are a bit heavier - For me, this is OK, because it seems to cause the tactile bump to be a bit more pronounced, which I like. Quality is great, and, for me, the board is hefty enough.
The only little complaint that I have is that you can't turn off the backlighting of the four Arrow keys, unless you engage the Numbers Lock. This isn't so nice appearing and a bit of a distraction when you are using the board without backlighting. Perhaps I am missing something, and someone who owns this board can tell me how to alleviate this problem.
For the price, this board is a good deal.
EDIT: Some might feel that the lowest setting for backlighting could be a little dimmer.
The "glow through" of the F1-F4 keycaps (interestingly, the backlighting control keys) probably indicates that these keycaps were painted separately from all other "batches" of keycaps.
