I got an IGO-L for my first dripper, cost me about 10/12 wuid delivered, and after mastering it with cotton and drilling the air hole to 2mm, its probably the best flavour I get out of any of my attys (Taifun GT included)
It was recommended by T-Max (Snake oil vendor) and I am glad I got it. Took me a while to get it spot on though to be honest, but after trying 1001 different coils, I have settled for a "tricro "coil with cotton (Search on youtube for tutorial) its not as daunting as it looks to make, and the air hole makes a HUUUUGEEEE difference when drilled.
Also remember when using a dripper, drop your nic mg as it will blow your head off if its too high ( I usually use 12, and had to drop to 6 on my IGO)
