I want to add one thing to Sarah's list on the Hot Head: you can't adjust the flame chemistry, it's always got a reducing flame.
Here are some of my observations on some torches I've worked on.
Nortel Minor: a nice beginner's oxy-propane torch. It's easy to adjust the flame, but I can't get a pinpoint flame on this torch, when I try to adjust the flame to a very small flame, it loses focus and becomes an unfocused flame. Easy to do reduction.
GTT Bobcat: My favorite little torch. It burns hotter than the Minor, hot enough to do small boro beads easily. I can adjust the flame much smaller than the flame on the Minor without losing the focus of the flame, allowing me to work with very small detail. The Bobcat has a focused flame, so if you are looking for a bushy flame, this is not the torch for you.
GTT Lynx: It burns hotter than the Bobcat. I can adjust the flame to a pinpoint for very small work, but at the same time I can turn this torch up to work boro beads. The Lynx has a focused flame, so if you are looking for a bushy flame, this is not the torch for you.
