Heather,
to get some help from the list members it would be helpful if you'd let
us know in which corner of the world you are located. Your G-mail
account doesn't give a clue and you don't have a signature. I get my
non-fluorescent coverslips from
http://www.hecht-assistent.de/ (Order
no.:1014) but I am not sure if you would consider ordering in Germany.
Also, you might want to let people know which decon software you are using.
