How sturdy is your bench? A little bit of wobble isn't too bad with a single stage press. If and when you go progressive, you'll want a rock-solid bench to mount it to.
My wife that lil table will work til Father's Day. I even thought about building my own. My dad and I built one from scrap wood at our old house and that stayed with the house. The house could blow down and that bench will still be there.
you may find that that you'll have to "tinker" on your Lee every now and then to keep it running 100 % ....(changing the auto index plastic gear, etc ) but I have 4 Pro 1000'a and one single stage something like your and once you get the feel for the Lee machines ...you may never dream of Blue again ...
