I like the Opus BT-C3100. Basically a do-it-all charger.
You can charge two of your 26650 cells at 2A using the two outer slots. For 3-4 cells, it will max out a 1A. You can go all the way down to 200mA for small cells. With all the other functions, it's a steal for around $39.

What about a Nitecore d4 charger?
[Nitecore D4 is a] Solid reliable charger [...]
Apparently not always reliable. Iirc there are many reports of units that have burned or melted down, e.g. a quick search located this and this youtube video, where both users had the 3rd slot burnout. It's not clear if these are genuine or fake units. The C3100 does not have such issues, i.e. no fakes, and I don't recall seeing any reports of burnouts or other safety issues.
The mc3000 is the daddy, but reports of build issues have kind of put me off that..............Just too add, none are perfect, all have an issue or reported issue from buyers over the year/s........................as with pretty much anything .
Anything in particular about the mc3000 that stands out as a problem? The one thing with mine is the sticky sliders.
Off the top of my head which i remember reading a few issues about, yes sliders, plastic breaking(build quality on cheap side). Thats what put me off with around a $90 price tag. Other than that, i like the options and flexibility. In truth i would not use 1/2 of it..............heck 3/4 of the options. 99% of the time i just want to charge cells, chuck in and charge. So it would be wasted on me anyway.
