I'm looking to get started with gas welding and am at a loss for what equipment I should invest in. Looking online, I can spend anywhere from $100 to $600+ on torches/regulators/etc. I guess the real question is: why DON'T I want the Harbor Freight welding kit special? When the whole kit costs as much as the Smith torch handle, I get suspicious. Is there any noticeable difference between a $30 regulator and a $100 (both are single stage)? How about torches?
