The pricing looks about right based on the gear. REC should be most expensive, and ABB (now Fimer) also has a more premium price.
Should you go with the more expensive option? That’s the tough question, it’s really a personal choice. We rate REC very highly. I’d personally probably choose the last combo, $1000 is a small difference to pay for something that’s going to be on your roof for maybe (hopefully) 20+ years.
