I would suggest the Sentinel. You might be able to pick up a V3 of the Sentinel at a cheaper price. Also, I would suggest a tank based atty also as that is great for when you are on the go like driving.
I completely understand where PBusardo is coming from. Before I learned of vaping, I saw someone blowing massive clouds on a tank and I thought that it could not possibly be good for him. Of course now that I am vaping myself, and I've learned more about it, I know it's not that bad at all. But the majority of people still won't understand, and it really isn't going to help give vaping a good rap because to the uninformed, that vapor cloud isn't any different to smoke.
I puff on a Vanilla topped with an Immortalizer with a 0.8Ohm coil. I'm in no way puffing clouds as large as some of those in YouTube, but I still turn some heads when I vape on our building's smoking area. I can't help but think that the same thoughts I had are running through these people's heads. When the masses know more about vaping and how it is so much less harmful than smoking analogs, then this won't be a problem at all.
Personally, I do not find offense with Mr. Busardo's little rant on YouTube and I found his little joke at the Legal Vape 4000 video quite hilarious. I don't know of any other vaper here who took offense with that as well.
People have different reasons for chasing clouds. Some genuinely like to vape that way, while some just do it just because they can. Some do it to prove or test a device's capability while some do it to merely show-off. My hat goes off to those who simply want to push the boundaries in atomizer and device set-ups to increase vapor production and flavor in a safe and responsible manner.
That said, I'm really impressed with the quality and workmanship our local mod makers are putting into their devices. Having owned one, and having held several others, I find that most of them are solidly built with pretty good finish. I was tinkering with the idea of making my own mech and speaking to a friend who owns a machine shop, it isn't as easy to do as I initially thought. A lot of effort and attention to detail goes into getting these things just right.
