I used a nice SS drip tray with a removable grate, for a few years. If you don't clean it very regularly, it turns into a stinking, sticking, festering mess. Took a tip from a lady brewer in our club who just puts nice throw rugs on the floor in front of the fridge, under the taps. Catches drips, comes clean in the washing machine. Been doing it that way for years now.
