50$ for my mod, + 34$ for the tank + 10$ for my sony vtc5 battery to power it. I only need to rebuild the coils for the lemo tank which is super easy, it hits like a dripper which gives AMAZING flavor, one of the best tanks on the market atm and will be for a while. All for under 100$. Granted I need to build my coils, but I can put out clouds which will beat some drippers out there. And the taste ... mmmm amazing. (though it sucks down juice) Ultimately it will come down to what you want, and what you are willing to spend. But in this field, if you are nit picking over 10-15$ ... just spend the extra amount and get something better.
Seeing what drunkenbatman posted, I can see where using pre-built or building the coils are cheaper.
I'll probably end up with the pre-built ones as I have very shaky hands - and bad eyesight XD.
All of this has been a really big help. I kinda wish I had asked ahead of time before buying anything. Costly mistake
