Mechanic parts questions

I just recently hit level 100, (I know not a great feat) and I was wondering if the Golden Mechanic parts were worth hunting or not? I have hunted everything but the transistor and the leg, and I'm only really interested in the leg for the speed/jump. I guess the DEF is important, but with these recent events I have over 500+ Reindeer Milk at all times.
The set gives me +2 Weapon ATT and +4 to all stats, but is it really worth my time to spend 1~3 hours for one piece?
