To be perfectly honest, if I could not afford a Provari, or other highend device I would simply replace my MVP2 with another MVP2 when it died. The MVP2 is a solid device and does what it does well. Your Provari, if you choose to eat Ramen and Peanut Butter for a month beats all else
for the bulk of mainstream vaping It will most likely outlast anything out there.
The MVP2 will most likely outlast any Vamo/Vmax/Zmax/SVD purchase, the batteries you will buy for vamo/vmax/zmax/svd are going to outlast the devices. This is not a wild claim, just fact and personal experience.
Yes a cheap mech clone + a cheap clone kick is another option as well. A replacement MVP2 will probably outlast the threading in even the better quality Nemesis clone. Again, personal experience.
There is a new player on the block that supposedly is of some quality worth mentioning.

As you can see there are a ton of opposing view points on all this. You have people who regularly spent 400$ a month on cigarettes calling anyone who spends 200$ on a vaping mod that will outlast any 3 cartons of cigarettes a fool...
Everything mentioned here is a valid option, 90% of them are valid temporary options. You just need to pick the one that is right for you.
