We have the marquis gold 5500 lp. We also wanted lp as I don't want to be carrying gasoline around. In our old unit, I had the portable honda eu2001's, but we ordered this new and wanted the permanent unit as well. I absolutely love it! It's quiet and quick to use without having to take the portables out and plug them in.
