Glad to hear you're moving in the right direction (at least for me it's the right one).
There's no "good Ohm rating", it all depends on the atty you're using on your mod, on the battery you're using in your mod. For standart batteries (5Amps) you can get down to 0.8 Ohms I believe until it gets a lil bit unsafe to use (sure if you got your vent holes on the mod and since you don't vape 0.05 Ohm build it should be fine even to vape 0.4-0.6 Ohm coil on a regular 5A battery, but seriously, you'd better not do that for safety reasons).
A good Ohm build on a MVP is whatever from 1 Ohm up to 2 Ohms I suppose since it's a VV/VW device.
This info is pretty off base. No offense to whoever posted it, but I find multiple areas that aren't sound advice. First lets handle the easy one. If I can recall offhand, the lowest Ohm an MVP will fire is a 1.2ohm coil. Obviously you don't want to go below that. Though some people have successfully ran a RDA on an MVP (youtube dripper on am MVP for proof), it is not personally recommended because it will not push the power you need for it. That being said, it would probably be a safer way to start learning to build your own coils, since it is a regulated device and has abilities to prevent batteries from venting.
Another note about the MVP, is that while it will read the resistance of the coil to a certain extent, it only reads to the tenth place. Most devices and ohm meters that read to the tenths will round up or down, so any coil reading 1.2 ohms may in fact range from 1.15 to 1.24. This inconsistency would be fine for that ohm level, but when we sub-ohm that accuracy becomes an important factor. That is why I recommend an ohm meter that will read to the thousandths place, and doesn't have a high level of variation. Some readers have up to .2 ohm variation, which could make a coil read safely in the .3 ohm range, but could potentially be a .1 ohm build that is UNSAFE (imho) for ANY single 18650 battery currently on the market. I personally use a meter that goes to the thousandths place, and leave a safe margin of error for my 30 amp continuous battery.
Here is a chart I use to look up batteries and their continuous amperage rating, however it is a little dated, so newer batteries have been hitting the market.
Here is another chart to see what amps a particular build will fire at.
I always read this chart from the 4.2V line, since that is the maximum amount a battery will charge to. Any build that shows an amperage rating over 5 amps on the 4.2V line is unsafe! (I would tell you specifically what Ohm, but cannot type this and view the chart at the same time from my phone. May edit it in later). **If it is the 5 amp continuous rating that was mentioned here, it doesn't need to even go down to .8 ohms. At 4.2V, the amps are at 8.25 which is unsafe in my opinion. Read the ETA down below for more info.**
As for beginning with a mech, I ALWAYS recommend reading up on Ohms law, as well as battery safety. Once you have read about it, read it again! It is imperative that you know these things so that you can vape safely without any repricussions. One expert on here that I would highly recommend is Baditude. I have read his stuff multiple times and seen him post on threads like these more times than I can count. He has tons of experience with battery safety and how to do things the right way. Search for him and his blog posts for the "homework" I assigned earlier.
Finally, enjoy the hobby and everything that goes along with it, just in a safe and respectable manner! Oh yeah, and welcome to this amazing forum!
ETA: when I read the battery chart, there was only one samsung in the unprotected 18650 section, which was the 2000 mAh one. If that is the case it is a 22 continuous amp battery. If it is this battery it 'should' be able to safely handle a .2 ohm coil, which uses 21 amps. That is still a little too close for me personally, and I can go ahead and tell you that my .212 build (safely run on a 30 amp battery) is a very warm vape! Also, I would recommend starting at a higher ohm build and slowly work your way down if you prefer. Somewhere around 1.1 to 1.5 ohm build at first, or if you insist on sub-ohming (and have a battery that can handle it!) in the .6 to .9 ohm range.
