You make some good points, though I’m not sure that most people riding around even know what TIG and MIG are, let alone how they’re different. Armed with this knowledge and presumably fabrication experience, it certainly would be cheaper for you to make your own frame from scratch.

This wouldn’t be the case for a person that’s never used a welder before or thought about the foot cost of steel tube. Which is where this company - or any company, really - is making their money.
