Most inexpensive clearo and how many times can you change the head?

[shakeytails]

I'm new to all this- went smoke free on May 10th. I have a 900 and a couple of 650 batteries from fasttech. I'm broke and they're cheap. I have a few ce4+ clearos from my first order- 2 died and the one that's still working leaks at the bottom (onto my battery) when I use it, and it gurgles a lot too. I just got a 5 pack of ce4(non-rebuildable) clearos and they're working great at a cost of something like $1.30 each. So, I'm thinking even if I change the heads on the ce4+ clearos they'll still leak fairly quickly, correct? Should I just stick to the cheaper ce4 and throw them out when they die?

What about the fastteck evod clearos? How many $1-ish head changes can I get out of $3.66 clearo before it completely dies?

Just looking for the least expensive alternative, especially since I'm still at the point of trying new juices and like to have several flavors loaded up to switch throughout the day.

I also bought an SM20 dripping atty from fasttech, but I'm afraid to use it because I don't have a multimeter and I don't want something blowing up on me. I'm think getting into rba's will NOT be my thing.

vivi novas seem $$ compared to the c4, but they are top coil and work really well. Easier to change juices on a replaceable head clearo too. EVODs are awesome and i'd highly reccomend them, but the vape is a bit cooler.
until you have 2 sidebyside though, you won't notice a difference.
