I'm same height. 6'5". My lathe is OK for me (Taiwanese AL960B, pretty much the same as the Grizzly G4003G) but my old RF30 mill drill is a bit low. It's on a frame on castors and nearly all my work gets done in a vice on the table so that all helps, but from time to time I find myself sitting on a chair to do some jobs. I've got plans to get a new mill eventually so Ill put up with it until then.
Recently my wife was away for a week, she said she left some frozen meals in the freezer for me. For the life of me I couldn't see them in the big freezer bin. I turns out there is a set of drawers in the freezer immediately under the fridge section that I never knew were there, just right for short people.
