JDM TD-X was magnesium and pretty much a TD-Z minus some bearings, non-clicking cast control cap, non-metal drag star, different ported aluminum spool, among a few other minor differences. Very good reel as is or could be upgraded pretty easily to get pretty much TD-Z performance. They originally retailed for around $250-$300 depending on the exchange rate. I would definitely go for the 103. As far as trading the Zillion for the 105, that really depends on the condition of the Zillion and what you want/need more. The Zillion is a known workhorse, where the TD-X 105 is less of a brute and more of a finessey reel.
