Hmm... I just ordered a Happy Hacking Lite 2 keyboard, which uses a membrane switch. The HH Professional uses a mechanical switch, but the ~$250 price scared me away. I also looked at the Das Keyboard and the Unicomp Customizer, which are both mechanical. Has anyone used both versions of the Happy Hacking keyboard? Is there really a huge difference in the feel of the membrane version and the mechanical version?
