Just in case anyone wonders what the dangers are of inhaling burning/metling foam fumes, I did a little bit of a research and found a lot of good information:

The thread includes links to many government websites, some of which provide instructions on what protection you should take depending on the amounts you're working with.

Regardless of any research, always use common sense and be safe. This is a fantastic hobby and it would be a shame for it to be something that caused any health problems.

Simple AC 25V 2A Power Supply which can be regulated by a dimmer switch. You can use it for your foam cutting needs or even a soldering iron (to regulate its heat). Shopping list is included in the HowTo Videos towards the bottom of this thread. That guy does a fantastic job explaining this simple, yet awesome setup.

In this thread I describe a way of using plastic forks from cheap foam brushes as control horns. Thread includes diagram and a fairly good explanation of what needs to be done. It's very cheap and easy. As other members have mentioned, you can buy those brushes from Dollar Tree and other cheap places and pay very little for excellent control horns.
