I can translate it for you..
28,000 - Chassis kit
31,500 - Original Set (Chassis kit + Titanium)
35,500 - Full Set (With Amp)
I guess it does include a ESC as Ultragraffics said, thats if they refer to ESC's as Amp's here!
I stopped by the a couple of shops today, they had plenty in stock just waiting for someone to buy them!!
Here are a few pictures for all... Sorry about the quality, they were taken from my phone!
