I got frustrated with the EGo atomizers also.
My best set up is a tank/carto. The carto goes inside the tank, keeping the carto nicely moist with juice all day. My tank holds 5 or 6ml.
Here are some examples of nice tanks:

I have one of these and it looks pretty awesome in my PV.
Any time the topic of glass tanks comes up, people naturally wonder about breakage. I wondered the same thing. Who would want a jagged broken tank full of nicotine juice in their legs, right? These tanks are durable.. Watch these videos to see torture tests:

The secret to the strength is annealing. This is a heat treatment used to strengthen glass. If you buy a glass tank from any vendor, make sure it is annealed.
Another often recommend vendor for glass tanks is IBTanked. These cost less than the Phiniac tank. I don't own one, but another guy on this forum who knows his stuff recommends these and owns several of them.
I also own a locking tank. It's plastic but works well. It's my back up system.

In short, if you are frustrated with the EGo atomizers, it's probably time to move on. With the quantity of juice you consume, a tank may make the most sense.
If you prefer to use something other than a tank, PBusardo just completed a review of clearomizers. The Kanger T3 came in first place. These are for sale for 5-7 bucks at several vendors. The T3 has replacement heads, so you can change the head when it gets old.
Please excuse typos.
