Don't know anything about the site. Reading what is on the net suggests they MAY be sketchy. I went to Harbor Freight and bought a Predator 3500 Inverter/Gen for less than $700 on sale. It's a Honda clone manufactured after their patents expired. Used mine to run the entire rig including a 15K A/C. It's quite and runs forever on no gas. I give it two thumbs up.
