Our local Lowes used to sell for $200 10-circuit transfer switches
bearing both the Briggs & Stratton and the Cutler-Hammer logos.

Recently they switched to a 6-circuit one (an EmerGen 6-7501, IIRC) for
$200, but they still have one of the 10-circuit ones on clearance for $150.

Both are 7500W 4-wire (240/120V) manual switches.

Which of these is better value for money, or should I look for an
entirely different model somewhere else?
