Valve tool availability

[djbender@domain.elided]

     Does anyone have, or know where I can find, the tool for 
     removing/replacing the valves on a 4-cylinder Alfa engine?  Is it the 
     same tool for a 6-cylinder?
     
     I borrowed the one my mechanic has.  it's about 10)X better than the 
     "C-clamp" tool I got at Sears.
