I've been on the
nautilus bandwagon for more than 5-years myself. I gather you missed out on the stainless steel replacement for the glass
tank? It's been a couple years since I've seen them available, last time at myfreedomsmokes for only $3 each. Indestructible. I'd buy a couple more if they'd show up again somewhere. I've got quite a collection of the glass ones from buying the glassomizers and switching to SS before using them, LOL.
Aspire K3, this is new to me. At a third the price, I may have to get some of those, even with the capacity of only 2ml. I'm stocked up pretty well with Nautilus atomizers. As you said, at this price it's kinda hard to ignore, even though it's only 2ml. I've got some of the 2S
tanks, and the top-loading is great. But, they cost as much as the full-sized Nautilus.
