I just recieved 20 packs of these from FT. The price was great and they are authentic. Cheaper if you but more than 3-4 packs. Remember that CC and PayPal are not options with this Aspire product, so you need to use Bitcoin or a GC.Hey @Skold, I bought the coils from someone in the classifieds so unfortunately not something you can get all the time. The classifieds here are a gold mine though so I would suggest watching that forum just in general for cool stuff.
I've heard the clapton coils don't last very long for many but I haven't tried them enough myself.
For the cheapest option to get the 1.8s probably fasttech is your best bet. It is China so will take a while to deliver but if you plan right it is a great choice and cheap as chips:
$7.74 Authentic Aspire Nautilus 2 Clearomizer Replacement Coil Head (5-Pack) - 1.8ohm (4.2-5V) at FastTech - Worldwide Free Shipping
With ePacket shipping (a $0.50-1.00 upgrade), I get all of my FT packages within 2 weeks from China to Toronto, Canada.
