That's quite a low price for an Inspire 1. Your best bet is to set up an automatic search in E-Bay that e-mails you when an available Inspire 1 comes along for that price range.
For $1700, you might have to be willing to buy one that's water damaged or crashed I think Unless someone really needs to move one quickly and needs the cash really badly. Good luck.
I am selling my Inspire 1 V.1 Type C, bought it in Sept 2015, here are the ebay link. Actually I have 2 Inspire 1 so selling one of them. Have a look and happy bidding.
Nate, not sure if you've found what you're looking for, so if not then check out my listing on eBay for a nearly new Inspire with all accessories. The current bid is only $1,704.00 and 14 hours left before the auction closes, so check it out! Happy bidding! DJI Inspire 1 w/ camera, New battery, New props, remote, case, etc. (Immaculate)
