Finally found a cheap brown cherry keyboard dirt cheap compared to the japanese new alternatives
http://sandy55.fc2web.com/keyboard/mx11800.htmlThis is exactly the same keyboard, and i got the keyboard for £15 used (~$30). The tactile feeling is not as great as the blue stems, but it does have alot more tactility than my steel series 6g and less resistant. Its a semi-compact keyboard in that it isn't as long as normal full sized keyboards but its wider making it much more bag-able. Not sure whether I will replace the g84-4100 for travel use as its still fairly big.
The ebayer didn't know if it was brown stem and I was taking a gamble it was a brown stem. Other things though is that due to use, it has some wear marks, and also its in the dread US layout. Haven't typed on it yet though
Don't know whether it will replace my blue stem either, but now I can confirm I own the black (MX +ML), blue and brown stem cherry switch based keyboard
Now the rest is capacitor (topre/hhkb), buckling spring and alps i will eventually get some time down the line.
edit : as per the site above i can confirm the space bar has a different coloured grey stem, it feels more heavier than a blue stem, similar to a green stem cherry, but without the sound. Not sure why, but i prefer the tactility of the switch over the brown stem, but it is much more difficult to press down. I'm guessing spacebar keys have alot more pressure
