ADVICE PLEASE

Need some advice as I am helping a friend to find the right bike/frame:

• 700c CX frame
  
• disc only
  
• steel
  
• horizontal dropouts with 135mm width.
  
• nice forks (i.e. no ugly unicrown style)
  
• off the peg
  
  

Only one that ticks all the boxes so far is the All-City Natural Boy Disc, but that seems to be sold out everywhere.

Any other ideas?
