"The Shuttle, Soyuz, and the Proton are the closest thing to HLLV currently and they are a distant second to the Saturn 5 and Energia. The boosters you mention are not even close. Maybe you have a different definition, but HLLV's are not in commercial us by my definition unless I've mixed up units somewhere. "

Closest thing presently to a Saturn V is the largest Delta IV. Soyuz isn't a large booster. Proton is in same class as Delta IVH, Ariane V, Altas V, and the planned largest booster from China. These boosters can put *about* 10 tons of payload to GTO (or a lunar trajectory).
(btw, I don't know what HLLV stands for but HLV stands for Heavy Launch Vehicle)
[Saturn V put "Payload: 47,000 kg. to a: Translunar trajectory"

Saturn V was about 5 times bigger than any current HLV (the Shuttle is about 2/3 the Saturn V mass but it's limited by it's orbitor's dry {or dead} weight to LEO]

"How you think we can do a Moon mission with commercially available launchers is beyond me.

Once again (for the hundredth time) here's an article that talks about how you could have gone to the Moon without the Saturn V:
