Do I really need a multimeter or can I just check the ohms of rba's on my Vamo?

I'd recommend the multimeter but, if I am correct, the vamo has short circuit protection so it would seem it would be okay. The concern with not testing after a rebuild is some don't have the protection and it is possible that the kanthal is touching something it isn't meant to meaning those type will fry the board. I learned that the hard way on a head that arrived with a short. Oh well, egos are cheap at fasttech.
Seems right to me, you don't NEED a separate meter. But I find it a bit more convenient. I can rebuild several heads and test them all just by moving the test leads, don't have to mount, test, unmount...
If you do any kind of household, or automotive work, you might find a DVM useful for checking the RESISTANCE value in Ohms of the coil.
Personally, I would not trust one of those units, especially considering I have o-scopes, spectrum analyzers, dvm's, and just about any other piece of electronic test equipment at my disposal.
YMMV
Indeed, even a low end DMM has multiple uses. Like verifying the Vamo is really putting out the volts is says it is 
A DMM to me is a Must.
I'd rather use it than a Mod. And a DMM is nice to Check Batteries with that don't go in a e-Cigarette. Or to test a Wall Outlet.
And a DMM sitting on a Work Bench or Desk really makes it look like a person knows what they are doing.

When and if you Vamo dies you multi meeter will keep going and as mentioned its got lots of other uses other than vaping.
People will be shocked when I buck the trend. A DMM is NOT required for your RBA...if and only if...you use the RBA on the vamo exclusively. Meaning you don't also use it on a mech mod. However, if you have several PVs and batteries, or have a mech-mod in particular, it IS required. Too much stuff to test not to have one. And you need it for more than checking coil ohms. Like mech resistance, button resistance, checking voltage, etc.
Very handy device.

Before going out and buying a multimeter, look around to see what ranges the available models are capable of. Multimeters often don't give accurate results for very low resistances, and you'll need a fairly good one to get good readings. The $10 ones that they sell at the hardware store will probably be useless.
I did a LOT of research prior to setting up my first RBA. Two of the "requirements" that the experts were recommending at that time were a digital multimeter to test coil resistance and a minature butane torch to oxidize the stainless steel mesh and wire. Despite owning a Provari that has a built-in atty meter, I got both the DMM and a micro torch.
I've been using the Provari for measuring my coils since I started and the DMM I bought is still in the box. But then, I'm not making sub ohm coils - that's another topic altogether. I've used the micro torch in the beginning, but since then the current common theory is you don't necessarily need to oxidize the SS wicks anymore.
I've gathered a lot of information resources that you might find helpful as a new RBA user:
