Duty cycle is often overrated for most users that aren't welding pipe all day long out in the field.

Do you know how low the duty cycle is on your Thunderbolt?

What do you plan on building?

That said, if you are seriously looking at the next level, the MM210 has about the greatest reviews of any machine out there.

If looking for more portability, my Passport is for sale.
