Have you really tried them? For me, mechanical keyboards are among those things in the category "You don't know what you're missing but once you know, you can't go back." Like heroin, I guess. Buckling spring probably not, but maybe some Cherry switch would be just the right thing for you. Anyway, before I got my Unicomp I had no idea how bad other keyboards were, especially laptop keyboards.

Coincidentally, I've retired my Unicomp yesterday to save desk space in exchange for a Pok3r with Cherry blue switches. It's one of the few mechanical "hipster" keyboards that allow you to put Ctrl next to the "a" letter, where it belongs. (HHKB has this built-in, but it's just too expensive. And it's also not programmable.) Unfortunately, the Pok3r has one disadvantage: When you set CapsLock to Ctrl and L_Ctrl to Fn, then Fn+Ctrl key combos don't work properly. So I'll have to change Paredit keybindings in Emacs. :/

It's a pity that Unicomp doesn't produce a tenkeyless keyboard.
