gee, I make one comment about how good gasless mig is, and stubbbornly ignore all of your valid recommendations about using gas, and I'm suddenly the no.1 gassless ticketholder? :).
Admit it Marty, its better on the dark side and not having to constantly buy refills will save you pennies for more toys or filament!. Even Dave's Garage is a convert. It does with the cleanup to use anti splatter spray, I just forget each time.
Not having played with one, the only thing I see about the pin puller, is being able to cleanly remove the pulling pins afterwards, otherwise I dont think i'd use one enough. I'd probably just spotweld a few tabs on and then use a cheap slide hammer or MCGyver something.
I like the deisle heater though, thats definately on my wish list before too long.
