MOTM

Hi folks,

I don't post much here so I hope you'll excuse this OT question.  I 
have a large, heavy keyboard in a case that I need to ship 
(57"x21"x11").  I'm having trouble finding a box anywhere near that 
size.  Anybody know of a good source?  Also, would you recommend bubble 
wrap or peanuts or something, or is the case (skb plastic style) enough 
protection with a cardboard box around it?  Will be shipping via DHL.

Thanks,
Larry David
