Here is what I found so far for anyone interested:
Mini Vivi Nova - Vendor description specifies polypro tank:
Lite Cig USA - $9.95 - Out of Stock
ejuice Monkeys - $9.95 - Out of Stock
Vapour Solutions (Canada) - Smoktech brand: $13.95 - In Stock
Mini Vivi Nova - tank material not specified...
SmokTek - Vision brand ("newest version...V3"): $11.95 - Out of Stock
SmokTek - Smok brand ("new with this design..."): $8.95 - In Stock
SmokTech Mini Vivi Nova 2.5ml Tank Clearomizer - 510/eGo Compatible, Replaceable/Rebuildable Coils, spring loaded center pin.
Honestly, my eyes just kind of glaze over trying to compare pictures and such - if anyone can tell me if the Smoktek Smok brand is polypro or not I would be forever grateful.
PS-I found some places selling the regular Vivi Nova w. polypro as well if you're looking - Monster Vapors, Vapor Kings, Lite Cig USA, Vapor Alley, and maybe Smoktek...
