To the left, find the Glyos Drop menu for December 12, 2012. The Syclodoc sold out in about 4 minutes, while the gold Aurustell Elite Armorvor sold out pretty quickly afterward.
Surprisingly, this new, larger run of the Stealth Armorvor MK II is still available. (Hopefully it isn't noticeably different, I skipped it since I have MK I.)
I suggest you visit the store now and see what's left.
