I have a friend that bought one 2 years ago and has had no problems.
  Ecologically speaking, perhaps it would be wise if we all had such a machine; 
the pay back time is another story... but, with any luck oil will get up to

heck, if we screw things up to badly, we won't have a place to have wars 
on..... argggg
