Right now any brand you get can be pretty good. I like DeWalt and Milwaukee but have a Ryobi ratchet with a DeWalt battery adapter. Ryobi was 40 dollars...couldn't pass that up. Watch the torque test channel and project farm as suggested earlier on youtube. Whatever you get, brushless is usually better. And look for battery adapters if you go off to another brand.
@Ozark80 i just did mine and will say it is messy and unless you have to do it there, i would wait til you have some other place to do it so you can take the weekend. Just keep feeding it the oil until then.
