DavidOck has a very good point. You don't even have to wind your own coils because you can get pre-made ones for very cheap. You can get a package of 50 on fast tech for a couple bucks and they are good coils.
But in reality, winding coils isn't really the hard part. It's getting them mounted on tiny build decks with microscopic screws! That's where I have the most trouble. Wrapping coils, wicking them, that part isn't so hard to me. It's just getting the dang coil trapped in the screws! So I can understand the problem if you have dexterity issues.
One great blister pack tank you forgot to mention is the GS Air M. I like it much better than the Nautilus and it costs about half as much, as do the coils. Plus the coils often last a couple of weeks for me. Great flavor!
You're so right Linda, it isn't the coil winding that's hard, it's mounting that tiny coil that's a real pita!
+1 on the GS Airs, nice tank for $10. Also has a TC coil available, economical way to explore TC vaping.
