I'm going to give you my

because I was RIGHT where you are, only about a month and a half ago! When I started, I did the EXACT same thing you're doing, I came here and asked for advice and honestly came out of it even more confused and frustrated because just about EVERYONE said DO NOT BUY A CIG A LIKE! And that's what I wanted, something small and discreet and it kinda made me mad that everyone was telling me not to go that route. I didn't listen, I got a V2 kit, LOVED the manual battery, as a noob, it actually lasted all day between charges and I was happy... to an extent.
As of today, I've gone through the V2 sets, ego/evod sets and a ridiculous number of tanks and a month and a half later, I did EXACTLY what EVERYONE here said I'd do. I now use a Sigelei Zmax mini mod and a Sigelei V3 telescope mod, I use Carto Tanks because they don't give me dry/burnt hits and I've been completely of analogs since I got those mods. I also use the Itaste VV V3 and it's a great device as well, love the smaller form factor of it and it's not complicated (not saying my Zmax's are, but for a beginner, it's easy to understand)!
I'm NOT going to tell you not to buy cig a likes, I understand what you're trying to do and if it gets you into the vaping world and off the analogs, it's serving it's purpose. I actually do still use my small V2 from time to time, I still think it's a great device for beginners, BUT the problem I had when I was using only that was that it wasn't satisfying enough, I would actually crave an analog MORE after vaping from it. I kept saying 'I don't want to use anything bigger than this, I WANT small and compact', but until I went to my local vape shop and they put my first VV device in my hand and said, 'sit, use it!', I had NO idea what I was missing. Everyone is different though, I'm not you. I'm so stubborn, I had to go through the steps on my own terms and even though I spent a lot more money then I would have if I'd just listened to these guys from day one, I don't regret it.
As far as the Mig Cig, I don't know much about it, not enough to say if it's great or not, I have seen a LOT of rave about it, but if those are your choices, I'd suggest an ego/evod. IF you MUST have a smaller sized 'cig a like', I agree that you should find one that's 510 threaded because you'll have more options that way, all of my tanks are 510 threaded, the ones I'm using NOW, with my mods and that is at least one way to save money down the road.
Feel free to PM me with questions, I'm FAR from being an expert, but I was in your shoes just last month! Sorry this was so long!
