I don't want to spoil the party here but the only people who are so price sensitive is outright newbies. Once you realize how cheap it is to vape, the thousands of dollars you can save a year with it, then $50 or $100 or even $200 becomes much less meaningful. In fact a lot of vapers go crazy here and end up with a table full of expensive mods.
Now if we think back to when we first started vaping, spending a couple of hundred bucks or more on a PV seemed pretty far out. Then we realized that it wasn't so crazy after all.
I started with an ego and to be honest I ended up hating the stuff and giving it away to someone, who I then felt sorry for. New people don't know the difference maybe but if they start out with a crappy PV then they are less likely to stick with it. I would not recommend egos a through z to anyone.
Sure, being able to twist it and change the voltage certainly can't hurt. This is however not what we would consider a good VV device, which you can change the voltage in small increments. Small increments can make all the difference by the way.
You can get actual VV devices so cheaply now that there is no reason for anyone not to start out with a good one, unless you are on a super tight budget. However, just by cutting down on smoking you can pay for several good ones in no time at all.
It wouldn't hurt I guess for someone to buy a couple of ego-c batteries, and you do need at least two of these, but the expectation is that if they stick with vaping and once they realize what else is out there for not a lot more money, they will be putting away the egos. So I'd recommend that people start out higher on the food chain, egos are the eels of the PV world really, the bottom suckers
