Hi, everyone, I'm a n00b here and would like to purchase my first mechanical keyboard in 25 years!
At my work I do ethnographic research, which requires a lot of typing. I'm a computer engineer by education, and occasionally write a bit of code as well.
I'm also an American living in mainland China, so that affects my selection I guess.
My previous kb was a Logitech G15, which is okay but keys started to feel mushy and I never used the screen; in fact after I upgraded to windows 7 I never even installed the software. I would prefer if my keyboard didn't need any software!
I work both at home and at an office, and in both places I need a keyboard that doesn't add too much noise to my fingers bottoming out the caps. I wake up early and don't want to wake my kids, and at the office we have 3 of my employees all in the same office so I would prefer to not disturb them.
So, from my research and reading of wiki's, reviews, etc., it would seem to me that I need a kb that uses cherry brown switches. Would you say that's right?
Here are some other thoughts:
I really love 'stuff' with a good feel of quality, so would love one that doesn't flex and creak.
I don't especially need a USB hub or gamer features. I press at most 3 keys at a time.

I think I prefer sculpted over flat, but it's not a deal breaker.
There are many nice things to say about China, but it is not a clean place. There is a lot of dust in the air, and your hands get real dirty doing just about anything. So less glossy is better (both the key caps and kb body) and would love if it came with a roof/cover thingy.
Media keys…I really would only use volume controls and wouldn't miss them too much if it didn't have them.
I have a desktop and a laptop that I might be using it with, so it would be nice if it supported both ps2 and usb.
From a casual browse around the resident buy-everything-website, Taobao, there's at least a couple of models of all of these: Filco, Dell, IBM Model M, Cherry, Steelseries, Ducky, Deck, DAS, PLU, HHKB, Jaki, Plum, Noppoo, I-rocks, Razer.
I'd like to not pay way too much for this; maybe there are even some models or brands that are cheaper here than most other places? What do you guys think?
Here are some sample prices of what I saw (I mainly priced brown cherries, but if you guys think I'd be better with a different switch I bet the prices would be similar):
Decks are way expensive here (or maybe everywhere?)
Filco Majestouch (Brown Cherry, FKB104M/EB ) is about 680 RMB (US$102)
blackout Majestouch for 950 RMB (US$143)
DAS Model S Pro is about 950 RMB
Ducky 9000 (Brown) about 700 RMB (US$105)
Ducky 9008 (Brown) about 750 RMB (US$112, blackout for a bit more
Ducky 9008 (multi: blue, brown, black) for 850 RMB (US$127)
Cherry g80-3000 is about 650 RMB (US$98)
'Plum' and 'PLU' mechanical keyboards seem to be cheap, but never heard of them.
Noppoo - never heard of them but they have brn cherries, abs/laser keycaps, and look exactly like many of the others, but they are cheaper at around 450 RMB (US$67). Anyone ever heard of them?
So, what do you guys think? Are brown cherries the way for me to go? What do you think about those brands and prices?
Lastly I did a search for mechanical keyboard (机械 键盘) and got random off-brand ones for less than US$10! Is it even worth trying them?
Thank you so much for your help!
