Yamaha DTXpress/DTXplorer/DTXtreme

Hi 

Im new to the list as I am just getting ready to purchase the DTXII 
as my first ever drum kit. 

Question for anyone who has purchased the kit from musicansbuy.com. 
They seem to have a great deal going on now where they are throwing 
in some extras (headphones, kick pedal, throne). Can anyone speak to 
the quality of these items - especially the headphones and the 
throne? 

Thanks for your time,
David
