Worst Parts Price to Total Cost Ratio Repairs

This weekend I had the timingbelt, tensioner, and waterpump replaced on my 2010 Honda Pilot. $1100 later, the car drives great and I have peace of mind for the next 100k or so miles, but it still bothers me that the belt cost $73 (and this is Honda dealer pricing, so I know it's higher than it probably needed to be) and the labor to replace it was about $600.

Yes, this included installing the waterpump and tensioner pulley, but the labor on those is negligible to me since all that has to be disassembled anyway to even reach the belt.

Is this about as bad as the parts-price-to-total-labor-cost ratio gets, or can you show me worse?
