I did a bit of research on PTO generators & I emailed HF with a few questions. A few things I liked were the GFI 120 volt outlets. The automatic voltage regulation module. Price. Also, what I found out about brush vs non brush seemed not to matter too much, the brushes are for the control voltage, not the output voltage, unlike the old brush motors. Here is a link for an interlock kit, does the job of a transfer switch manually, at a much lower cost:
