I worked with the Tissue Tek SCA Coverslipper at my previous job, and we
just purchased one at my current job.  We love it!  It is fast, easy to
use, and pretty much problem-free.  I highly recommend it!  One thing
you need to do is make sure your alcohols and xylenes at the end of your
staining process are very clean.  Any water or alcohol contamination can
cause the film to peel off of the slides.
