Oops, typo, u1253a had major issues. The 1253b looks great, and if the screen were to die tomorrow I could replace it.....but I'm worried about the screen dying a few years from now when the part is unavailable. At that point it becomes a paperweight. Pretty stupid idea on the part of Agilent.....and the fact that they carried it over to the B models is just irresponsible. Might be wise to go with Fluke or Brymen.
