Generators...What do you use at the track?

Yeah I,ve been looking at the Honda,s and Yamaha ones,but here in Canada,for a 3000 watt unit they,re asking upward of $2000.I did find a Powerhouse generator 3000 watt for $1300 at Costco.Comes with remote start and a bunch of other accessories.Run time is 7.5 hrs per tank.Still searching.
