I think eBay is often high. Many listing don't meet reserve and are relisted, competing bidders drive the price up when they get caught up in "winning", with constant nudges from eBay, of course. eBay or paypal get a cut, and some folks are just "living in a dream world" about what they can get. So look at actual sales prices, not asking prices, and see what's included. Check with dealers and CL listings, too, as the wise ones already advised. Just an example, the Pfaff Select 3.0 is currently on promo for $599 on the Pfaff site. There's an eBay listing for about $740!, no test drive, no warranty, no education, no service...livin' in a dream world! Posting here and on patternreview.com to see what others have paid or would be willing to pay is smart of you. Someone just did that about the (old) Bernina 830 on patternreview and got a bunch of answers.
