Optically they are all the same. That's worth knowing if the budget is tight! :)
If you see no distance markings on the focus rings it's the SMC DAL. If you see a red ring near the focus ring it's the HD DA with weather seals (the most recent model). Distance marks and no red ring it's the SMC DA (with green ring near the mount). Hoods can be bought and lost, and sellers might 'mis-type' or otherwise get labels wrong - but if you see the lens itself that's how you tell which is which.
