Golf Channel(Filmwerx Intl) only runs Hondas. Which they paint black/camo and remove all badging from(it's not a sponsorship deal). They ran short once and brought generacs to Sanderson. Let's just say that soured me a bit to the whole brand although I know they have a solid reputation and make good stuff overall. Personally, I run a powerhorse(yamaha engine from northern tools) pretty hard without a single hiccup in 3 years/seasons so far. The difference is -- you can easily get parts for Hondas at any hardware store. And will likely be able to 20 years from now. Whereas once parts are required for this powerhorse, I'll have to hope it's EXACTLY like the yamaha engines in the yamaha branded generators. But then again, I can almost perpetually buy powerhorses every 5-7 years for eternity just on interest of the money saved vs buying the Honda initially.
A couple of things that IMO make more difference than your initial picking. You'll want an extended run tank. You might not think it, but you will. When it's running your freezers/refrigerators in an outage, you won't want to wake up in the middle of the night to fill it up. Extended run caps are cheap on eBay. From there you just retrofit a boat tank and call it good. In this, the Honda is superior because it uses a vacuum fuel pump whereas my powerhorse is gravity fed. Not a big deal, but it's nice to be able to set the tank on the ground and not have to elevate it and worry about airlock.
Add an hour meter at purchase. They are on all the Filmwerx Hondas and it really helps with maintenance and is just generally nice to be able to look at. You'll think you know how much you've used yours, but after a year or two you won't, and will just change the oil every year anyway if you are like me.
Perhaps the most important - add a magnetic dipstick. Crazy that they don't come with one. The amount of metal particles which would have otherwise been circulating in the oil that mine picked up in the first 100 hours or so was really eye-opening. Has since slowed but still consistently has some.
Filmwerx runs those hondas almost totally trouble-free for 2000-2500 hours. These are running the cameras on course and all of equipment to get the signal back to the satellite uplink. That's not their full lifespan by any means. Just when they first start to see any problems whatsoever out of them. Pretty crazy really. As of Sanderson, I noticed those are also running on propane now.
