Wanted: a SS/Fixed-gear bike

Looking for a fully working and complete bike for myself.

I have been looking in this section for some time now but nothing appropriate has come by recently. I am 6.23ft / 1.90 m. and thus require something which is a bit larger than most bikes I have seen so far.

Kind of bike:

• Preferably something a la: Plug, Langster, Pista, Paddywagon.
  
• Straight handlebars would be a plus.
  
• Not too fussy about weight as I am too heavy for it to have any real effect.
  
• Brakes would be nice, as I use mine.
  
  

I am willing to pay** £400**. But willing to go a bit higher if I find something very worthwhile.

Thanks in advance!
