Are there any worthwhile tripod leveling center columns or base levels that are in use? Thinking about trying something on a Manfrotto 190cxpro.
I use two different types of levelers on three different tripods, for different purposes.
My "studio" tripod is a big heavy Bogen (now Manfrotto) that I'm not inclined to haul around out in the field any more. Emphasis on the word "heavy"... that tripod now lives on a dolly so I can roll it around, rather than lifting it. It has a pan/tilt head on top of a Bogen/Manfrotto leveler that's simply two thick, metal plates with three separate, knurled brass adjusting "dials" that can be used to fine tune level for careful and precise shot setups. It is similar to that "Nodal Ninja" leveler (

This type can be used on a tripod with a center column, in between that and the head. But I wouldn't use it with a field tripod because it isn't fast to use and adds a couple pounds to the weight of the rig.
Bogen/Manftotto now offers another type, that's loosened/tightened with a single lever (

In my opinion this would be a more practical type for use with a field tripod and will work with a center column.
My "field" tripods are Gitzo "Systematic" carbon fiber, two of which have no center columns, in large part because this allows me to use Gitzo levelers on them (older versions of
http://www.bhphotovideo.com/c/product/898087-REG/gitzo_gs3121lvl_leveling_base_series_2_3_4.html). These levelers are controlled by a single handle that's very fast use. A quick counter-clockwise twist to loosen, the same handle is used to adjust level, then a quick clockwise twist to re-tighten it.... That takes about 2 seconds. I often use these tripods with big lenses on gimbal mounts (a full size gimbal on one tripod and a heavy duty ballhead in combination with a gimbal adapter on the other), which need to be reasonably level to work well. This type leveler is much faster and easier than fiddling to adjust individual legs... Though generally not as precise for fine tuning as the other type of leveler described above. These do add some weight to the rigs... at least a pound apiece... but to me it's worth it for considerably faster setup, often on uneven ground. Now, both these tripods are plenty tall for me without any center column, which I also didn't want because it makes for an overall more stable tripod.
So, I'd have to say it depends... How you use the tripod and the type of leveler should tell you whether or not a leveler would be useful to you. And, are you willing to haul around the extra weight? From some of your followup, it sound a little bit like you may want to try a monopod instead... Perhaps with one of those simple, monopod-specific heads on it.
Whatever you do, the whole idea is that your supporting device is something you find as conveniently usable as possible for your particular purposes... So that you're encouraged to use it as much as possible and will see the benefits of doing so in your images.
EDIT: I've never used any sort of self-leveling tripod, am not even sure what a "leveling column" is, and don't use "pistol grip type" heads because they are just too light-duty for several of my lenses. Some of those might work well for you, though.
