I actually know the generator hustle personally.
Couple years ago we moved into our new house and 3 months later had a huge ice storm that left our community without power for about 1.5 weeks.
By the 2nd day I knew I was going to have to do something as I didn't want our pipes to burst and have to leave the house with our kids.
As I was driving out of town, I came across this guy that had a trailer full of generators that came up from Alabama just to sell them here ( he had watched the storm come in via the weather channel ).
He was selling each generator for $3k, these were $1200 units in stores like Lowes/Home Depot ( portable 9000 ones ). Even sadder, these were not new, but reman. units. However, I knew all the stores would be completely out of generators and gas was selling out quick in the local areas as well, so I bite the bullet and bought 2 of those fuckers.
Even though I paid a shit ton more money for them then they were worth, it was the best products I ever bought as I have had to use them multiple times already since then.
The guy who sold them to me had about 30 of these and sold every single one of them that day. I would think a reman. unit of that type prob only cost him near
Been thinking of doing the same myself.....
Edit, found it online actually...
http://titanindustrial.net/9000.html says the comparable price is almost $5k, but I see these same types in stores for $1200.
