What sort of torch setup do you all prefer for gunsmithing?

I'm interested in answers to these sorts of questions:
- air-fuel (plumbers torch) or oxy-fuel mix torch?
- propane, MAP, or acetylene?
- any favorite torch tips? Rosebud? Welding tip? Etc?
- any other suggestions for heating in the gunsmith shop?
