My budget is loose let's say up to 120.
I think I'd get it for both smoke output and for tricks so something that's decent in both those categories would be good.
I would like for it to include SOME juice to last me a little while.
I'd like a decent reliable model, and I wouldn't be opposed to building it myself as long as I had some instruction of some sort.
Alright then.
If you want both a good output for the tricks and a smooth coasting one for when ever then you NEED variable change, so that takes out half of your options, but don't worry the variable changes are better IMO anyway.
With a loose budget of 80 - 120 you should have no problem finding a great model with some juice. Even premium juices from the Cali district.
Decent and reliable are the two words that come to mind when I think of iTaste, I personally don't own one but about 60% of my friends have one that they currently use and not only are they great but I've watched one fall 10ft. plus from a make shift tree house in my friends garage and not even a scratch.
Models that are good that I know are as follow ( in your budget and seen and used them all):
iTaste MVP V.2
iTaste VV V.3
iTaste SVD (a.k.a the telescope)
Now the prices range from about $40 to $80 for the battery's or the kit's that stores offer. Personally I would choose the VV V.3. I like how even though its rectangular it still is more of a "stick" to hold on to for rips, where the MVP is a box. The SVD is a pretty good cloud machine but it's a little on the fat side and to put into your pocket looks weird. A huge perk to the MVP is that you can charge your phone through one of the ports they got on the side.
They all have the easy voltage change by pressing the plus or minus button and they all have an electric screen that displays the voltage and they all have memory to remember what your last setting was.
But for about $40 (depends what site you go to) on the VV V.3 you get the charger and battery with a manual (which you really won't need). Where the MVP is about the same price but key difference is no variable wattage. You need the MVP V.2 for that which is about $5 - $10 more.
It also has a puff counter, a battery indicator (the button you press to vape will go green (great), yellow (midway), and red (low)), 10 second cut off so it limit how fast you can burn a wick, you can smoke and charge at the same time, 510 threading (newest which you will need don't get any of the older types of threading), over charge protection (so you can't kill the battery by over charge), and you can change the voltage and wattage (volts by .1 and watts by .5 I'm pretty sure).
Make sure you do a little research on your own though to find what you like. I know N4N0 has the MVP and a more expensive model called the 134 so if you want first hand experience (long term) with the brand I would ask him. But the VV V.3 has my vote.
Now onto tanks. I don't think anyone will argue when I say just buy a KangerTech Protank 2 and be done with it. Nothing else compares to it.
For juices I usually go to my local shop since there juices is better then most places around me and a majority I've found on the internet. But Definitely check out FivePawns. You really can't go wrong with any of there juices especially Gambit. They are on the more expensive side but the quality is x10 better then 99% of the juices out there.
So the battery w/ charger is ruffly $40 and the protank 2 is roughly $25 so your about $65 into the cig itself, which leaves you tons of room for a couple bottles of juice. If you have any more questions just let me know.
EDIT: Forgot to mention I took the more expensive side when projecting the prices. So you will probably come out even cheaper.
