I can’t say enough about Generator Source. We were looking to sell a large diesel generator and found them on Google. We contacted 6 or so companies that all offered “hassle free” quotes to sell equipment to them. Generator Source was by far the easiest to deal with and really did provide a fair quotation from the start.
If you’re looking to move your equipment, this IS the place to contact. Don’t even waste your time with some of these other outfits like I did. They are fair, fast, and consummate professionals. Should the need arise in the future they will be my first call.
