You seem to be stating that a "party vape" is your first priority. If so, I would strongly recommend the Volcano as you said that price was not a major impediment. The Volcano blows a bad in about 25 seconds (Easy connection) while the Extreme is going to take almost three times as long (mine does). As others have mentioned, it's a no-brainer for those not used to vaping, as using a whip does have a learning curve that bags don't.
It is not the best personal vape (I like the Solo) but it is certainly possible to use bags for yourself. Getting a bubbler/bong is a great way of cooling the bag. Here is the adapter:

Vaporization is a delightful "hobby" which leads to the collecting of various vapes which becomes an "addiction"
