i use miller elites, with auto dark... for the money they are not bad... harbor freight ones tho.. are good starter helmets, helmets, u kinda get what u pay for, and i don't know about you, but i like to be able to drive home at night after a full day of welding (mig, tig, arc, plasma cutting everyday) without being flashburned.. and i have yet to have any issues other then the headgear is made of plastic bits, and u have to be careful not to pull ur helmet to high or pull it to low, cuz it will break the lil stop tabs. on mine i just drilled them out and put a ziptie, cuz i use my helmet only, and i like it in one place/the same place every time i put it on. luckily most welding supply stores carry Miller, and u can just get replacement parts all day. fairly cheap too.. harbor freight is kinda like, once u break it, throw it away.
if u weld alot, get a solar charged one, if u barely weld, get soemthing that solely relies on batteries.
