As someone that's been through more than 6 keyboards over the last two years, I really like the products Realforce produces. They do not have the "click" like a lot of mechanical keyboards, more of a "thunk" sound and feel. I'm currently using one of their newer models: http://www.realforce.co.jp/en/products/R2SA-US4-BK/index.htm... and have experience with an older one as well: http://www.realforce.co.jp/en/products/104U-S_XF01T0/index.h.... The difference between the two is the sound and feel of the keys. The older one is a bit noisier and has less of a "thunk" sound when pressed. I'd highly recommend either.
