The Scorpion (
http://www.glasstorchtech.com/scorpion.html) is different than the Lynx, but not in a bad or better way. The Lynx uses a different center fire (The Cricket) and then has an outer fire. The idea behind using a scorpion for making what we want to make is that you can use two oxygen concentrators (two M-15's is perfect) and the torch doesnt need tanked oxygen. Or, you can use an oxygen concentrator for the inner fire, and tanked for the outer fire. You can even use a foot pedal with it if you want. It's a very nice upgrade to the Lynx in the flame characteristics and size abilities, it's just a little different than the Lynx.
If you got a deal on the Scorpion, I'd jump on it, why not?
There's a friend of ours on Stickam that uses one for about 12 hours a day every day non stop and he can make waaaaaaay cooler stuff than I dream of right now.
