That's an old used car trick to change the price based on trade. It's alot of crap too. The price should not change if you're trading or not ...... anyone that thinks they are getting a great deal because the trade is inflated needs to educate themselves in the art of consumer protection and smart shopping.
I can get any of you a new 7000 for $3000US. Trades are accepted, and will be quoted at wholesale price ... if I SEE the trade. No trades will be accepted unless they are seen and tested first. The kn7k will be new and in a factory, unopoened package - full warentee ..... full Panasonic support.
Don't fall for that hype and unfair inflated prices. It's just a keyboard, not a car!
