I am now using an older membrane Logitech G15 gaming keyboard. It's not the best, but that display is awesome. especially with 3rd party plugins.
For my "testbench" (It's really just a random book, big enough for GPUs not to stick up at the end..) I use a tiny PS\2 Cherry mechanical server keyboard with a dead trackball (I use a mouse instead). It's really cool and I love the way it sounds. Although, for some reason, despite being relatively modern, it's missing a win key.
