Found a Cosmonaut at purecoils, Chef's website, also purchased a set of Aliens to go with it. Received the Cosmonaut today, installed the set of Chef's Alien coils, easy to install the coils, cut the legs to length, place them in the deck, tighten the screws, wick.
I thought the Drop was a great RDA. The Cosmonaut is even better IMHO. I am not a big RDA guy but the Cosmonaut and the Drop have totally changed my mind.
Current build is a pair of Aliens, .13 Ohms, 100 Watts and it is outstanding!
I did fix up the coils a bit better before wicking
