The thermal breaker on the Champion 2000i is there simply because it is required for CSA certification which is a requirement for sale into Canada. The breaker is a redundancy on this unit because of the internal software but was required by CSA.
Regarding the engine: The 80cc engine is brand new tooling and features.
Regarding quality: The member from the mid-west that saw the Champion unit in a Sam's Club. Please set the two units side by side. You will see that you DO get what you pay for. Please check again, side by side.
