   I have to mildy disagree with you. :)

   No more than any other oxidizer out they.  They all have diffirent bad   
   points.  Some are poisonous, some tend to freeze up equipment, others   
   require(?) high pressure tanks.  The dangers of peroxide are just diffirent   
   ones.   
      
   > it's impossible to buy the right grades (HTP)   
      
   Now you hit the nail on the head, even lower grades 35%-70% are hard to buy   
   over the counter.   
      
   > dangerous to make them,   
      
   Sort of.  First, note major chemical production of peroxide is done by the   
   ton lots, and I recall on only two major accidents with peroxide coming from   
   said producers.  One involved improper storage in a warehouse, and the other   
   the shipping tanker truck was not proper cleaned before the truck was filled   
   with peroxide.   
      
   The major problem, is that a lot of the 'production-handling' methods for   
   peroxide are trade secrets, and anyone trying to do it themselves basicly   
   have to experiment from day one.  I have had few problems with my   
   experiments, and no major accidents.  Even then, I now plan to build whole   
   new systems to processing peroxide that are very diffirent from what I first   
   started out with because of what I have learnt over the years.  Never in my   
   library research have I found any detailed information one how higher grades   
   of peroxides are produced for example.  Compare that to hydrocarbons, the   
   information of distilling/cracking oil to useful products is a flood!   
      
   > and it's harder to handle than people think.   
      
   There I disagree again, it is not harder to handle, it is diffirent to   
   handle.  You need a new set of safety rules to handle peroxide.  Note: that   
   both ERPS and ArmadilloAerospace have had no major problems handling it for   
   years.  Don't be surprise if Armadillo starts having all sorts of problems   
   with LOX because they are starting over and have to learn the handling rules   
   all over again.
