From my own experience, the originally shipped juice cart with the Cera was, if it even had a different ohm rating / resistance, functionally identical to the concentrate cart.
It was not very good for its intended purpose - atomizing smoke juice - which is why I remember them attempting to have another go at it. It's also why I stopped using it for juice and repurposed it as a backup concentrate cart.
However, even if it was perfected it would still be a $100 drip fed atomizer with an insulating design, both due to the cart construction and the ceramic shrouding, all on top of a proprietary connection.
Basically it would be useless to a vapor newbie or an enthusiast, entirely. Too heavy, too cumbersome, awful performance, entirely frustrating. The AVA was significantly better as a cheap dripper with 510. Paired with the small 6v double cr123as in the slick handle it was also a tight little package that was very light in hand. I only had experience with the high res (3.8-4 Ohm) but you could find a sweet spot every time for good taste and vapor production even for a small little mech mod.
There are a lot of kit options with cheap clearomizers that feature variable voltage/wattage/ohm checking that are half the price of a high end RBA.
Inokin has been blowing up as cheap ~$60 kits that closely emulate high end pv mods. iTaste MVP2 & SVD are super cheap and from what I can tell smoke (err vape) the old ego/egotwist setups for the money.
Johnson Creek also has the best juice around, unless you want something really exotic and even then it's best to try them at a juice bar / vape lounge instead of randomly ordering shit on the internet. Stay away from DIY flavors / mixes, it is a huge waste of time and will only prolong your agony sticking with analogs. I wasted a lot of time with that crap trying to find a good mix, guess what... somebody else already has a multimillion dollar business doing it lab-grade... huh
Now that I read your full thread title I will say when I canned the Cera I said "fuck it" and went with the ProVari & ZAP 2.1 RBA w/ ceramic wick, mainly because I figured if I had already owned an overly expensive and somewhat delicate "e-cig," might as well go all out and see whatsup with the gold standard vv mod. Also, because I could buy it all immediately and use it within a few days, versus waiting on a list for a high end mechanical and high end rba like a Precise Plus+ & a Kayfun Lite, for example.
You can get a ProVari with a protank or disposable clearos and skip their high end RBA, but at that point you might as well save the money on a cheaper mod and buy a few for your friends after you've experienced a good middle of the road setup, in my opinion.
