+2 on the Vapor4life.com suggestion. I've been happy with their products.
I'm assuming that by "liquid ones" you mean the kind that use the eliquid? All of them use the eliquid. The prefilled cartridges/cartomizers just have the liquid already added for you.
(Although save the prefilled ones. They can be refilled, as long as you use a similar type of liquid. For example, I refill my chocolate carto's with SnickerZ. You don't have to worry about it now, but it will save you money in the long run. After he gets the hang of refilling.)
The VaporKing setup from Vapor4life is easy to use and pretty reliable. They have tons of prefille carto's to choose from. Get a kit with at least 2 batteries. They do take some time to charge.
Hope this helps. Let me know if I can clarify anything I've said for you!
