We have used the Bio-RAD gel dryer for a number of years, and it has
worked very well for us.  We just place the gels (we never fix) on
whatman paper, dry for 45min to an hour and place it into the cassette.
However, I strongly recommend that you use some type of diaphram pump. 
Some people use vacuum pumps, and even with the traps etc I have
observed that these pumps have a tendency to be destroyed by this type
of use.

Good Luck
