I agree, the Para-Trimmer is the next best thing since sliced bread! I'll never go back to the knife again.
We use lid from one of the Ventana special stains boxes to catch the wax. I have also fashioned a drip tray out of the cardboard boxes that the coverslips come in.
We're all McGuyver's at heart, aren't we? :o)
