Dear friends,
  A colleague has asked me to advise on the purchase of a portable variable
fluorescence apparatus.  We have looked at specifications of the PP-Systems
OS-100 and OS-500 (made by Optisciences-Inc, U.S.A.) and are impressed by
the specifications (and price).  I also saw the devices at a conference a
while back.
  Our question is:  Does anyone have experience actually using these products?
How reliable and convenient are they in a field setting?

Thanks for any information (either replies to this newsgroup or to me
