I had one Dealer give me a great price on a D2 because he needed money for a vacation. When I called him for a Manticore he wouldn't budge on price, actually I think he wanted more than other dealers. Call around and find out who wants your business more.
I got mine used, but for about $500 I got the Nokta WHP, Nokta wired headphones, Wireless BlueTooth earbuds, and 3 coils. The LG15, LG28, and LG35. I'm pretty happy with the quality detector I got for the money.
