Ivee been looking into this pretty seriously...
Goggles - Yes... Controller - No
(*)
( also bare in mind you will need batteries and a battery charger , as well as drone)
### drone
as to which drone ...
I think it partly depends on where you want to fly it, and in what role.
many recommend smaller drones for learning on. these can be really cheap.
... so if its just practice, incl indoor flying - this could be the best way.
but for me, I want to fly outside where it could be windy so thats abit of a non-starter, also I want something that as my skills develop will still be useful to me.
my current thoughts are :
the new emax babyhawk 2 HD,
this is 3.5" which is a bit small - but the appeal is in < 250g ,pretty quiet
I think it could really compliment the DJI FPV well, as its almost everything the DJI is not
5" quad, there are a ton of ready to fly.
iFlight Nazgul HD is really popular.
however, Ive been looking at the Diatone Roma F5 HD
### Controller
so as above you unfortunately need a controller
the easy option, is to buy the DJI Controller v1, but is 300+ euros/dollars
this will then connect to air unit.
the other option is to buy another controller, and add a receiever to the quad.
this can work out a BIT cheaper (but really its still 200 euro/dollars)
e.g.
cheaper frsky transmiter +frsky xm+ receiever = cheapest
radiomaster tx12 + crossfire - nice option with great range.
an issue Ive found is availability in the EU - finding a drone + transmitter + compatible reciever really limits options. (US / UK seem easier)
reality is, drone + controller + batteries is close 750-900 euros...which was a shock to me - and the drone is really only 300-400 euro of that.
of course, once you have this setup - if you want another drone, you are all set to go.
(which i think is why many have multiple drones...
)
thats my thougts so far.... but as i say, Im just researching from a similar position as you.
hopefully someone will some experience can chime in with a low cost solution.

(*) there is some hope that an air unit v2 might come out that would be compatible with the v2 controller, but this is pure speculation at the moment.
also note dji recently, discontinued the digital fpv system, and said they were working with a partner (mostly likely caddix) , and there would be an announcement mid-april
though we do not know what that is.... could just be availability of existing products.
Im currently a bit 'on the fence', waiting to see what happens with the air unit... though I'll admit, its totally unclear... so Im finding it hard to decide how long to wait n' see.
I think for now, I'll way till end april, and see how the fpv drone landscape looks then?!
