Japanese steel: Nakagawa, Raizin, Ocean...and a Scapin?

Well, here it is. I've definitely been missing out by not riding more relaxed bikes!

Things to change:

• A headset from a more reputable brand (Cane Creek 40?) as the eBay special is garbage.
  
• Rear derailleur with a clutch (SRAM GX) as mentioned earlier in this thread.
  
• Small and simple front rack (Nitto M18/M1B/Bento) so I can lug my skateboard around.
