The 103 is a better wand than the 163, because the magic damage calculations in this game are one big tropical fruit.
Assuming you wouldn't be 'wasting' luk if you went with the 103:
103 - 60 mdef, 6 MP/level, .3 extra damage per spell attack, easier to find, lower level req.
163 - 30 avoid, aesthetics/novelty.
Functionally, they're almost equal, so why wait until level 163?
It's all pretty irrelevant though. The 70 is better than the 103 if you have anything less than 72 luk, and I'm not even going to speak of the 130.
I have a request, though. Can you compare a Shine Wand/Wisdom Staff to a 70/130 on off-elements?
