I haven't used the G15 screen for years (multiple monitors + kb is on a tray, so fuck looking down), but still love the size and general feel of it, plus the macro keys, which have a million uses if you're creative. I'd say get either the G510 or whatever the non-LCD equivalent is. Wish they would have kept the volume wheel on the newer models, though...

If you want CLACKCLACKCLACKCLACK nerd cred to impress your friends, go to Goodwill, find a Model M, take the case off and paint over the keys.
