Eleanor, are you still using 808s? If not, I can tell you that fasttech sells two kinds of EGO clearomizers that work well:
These CE5s (mesh cores)
and
these Iclear 16s (dual-coils with string wicks).
I have had an Iclear with my Erinmore homebrew and a CE5 with the very goopy Candied Cavendish running for two weeks. Still good.
I buy those FT CE5's every month and think they perform well considering their price. I've been pleased with mine. Out of 30+ purchased only 3 arrived DOA. The only thing I would say about them is don't clean them/soak them in vodka. I've tried this 3X and it resulted in about half of them leaking afterward. I think these are truly disposable.
