With the Gear Shifter re-released into the Crystal Shop, I'd like to ask if anyone knows the approximate sP value of it? Have you bought or sold one recently?

The cost of the crystals via user shops is 8.88m, so no more than that. Unfortunately I don't have a more accurate price for you though

HPCs are a pain to buy off the shop search/make from items.

I wouldn't go buying one expecting to dump it on the shop search for a profit, but I would put it up for sale for 12-15mil.

If an item hunter needs it, they aren't going to go frag 2K crystals if they don't have one.

Otherwise if you are patient and your buying, you can always go pay 8.8mil for HPCs and buy one like Darkrai said.
