Bought a pair from supergen. There are several models of the 2000. Got a nicer model with two covers and a parallel kit. Think it was under $1100 to my door.
Early 1999 F-350 7.3 DRW CC, 4.10 2016 Open Range Light FL295FBH 3 Kids, 2 Dogs, 1 Wife.
They are $499 less an 11% rebate right now at Menards, if you have a Menards anywhere close. That is a net of $444.11. That's the best I have seen for new ones.
SuperGen Products in Newark, NY. I'm lucky as I live ~45 mins from them. I bought 2 refurb'd units and the parallel kit from them many years ago and have been very happy with any follow up service that I've needed.
