I think you have to answer that question by answering a couple of other's first. 1. How often and duration of "power cuts?" 2. Depending on the answer to 1., what is your motivation to have a genset? Power a well pump, furnace, frig and perhaps separate freezer? etc. Personally, I have a genset primarily due to having a large side by side frig and a upright freezer and an extended "power cut" would cost quite a bit in spoiled meat, etc. Also nice to be able to have tv, computers, etc. I went with a Generac 3750W for about $300 12+ years ago and it's still going strong. Not the $1600 (If Google converted it right) the Honda would cost. The lower priced unit you have may suffice. Only you can answer if you need the increased reliablity, etc. a Honda would provide.
Have you done a test run with your existing unit with vital loads to see how it and everything worked?
