If it was me I’d prefer to buy at the local dealership for quick/personal service if/when required….but $1000 is alot of money. I don’t believe the quality should be any different regardless where you would decide to purchase. However, a dealership would steer you to the correct generator to meet your needs. Get a quote in writing from Home Depot and then take it to your Honda dealership … bet they’d meet it, unless there’s something we’re missing. 🤷Keep us posted.
