I don't want to be a wet blanket but I have to echo the calls for caution. Do try it out if at all possible before buying.
For sure the sense of "presence" is great, E D in VR certainly shows the true scale of things. Unfortunately I found there were too many drawbacks and was very pleased to be able to sell-on my Rift for the price I paid for it.
1. Resolution - being used to pin-sharp 1440 monitor images the low resolution in the Rift is a real disappointment.
2. Screen Door - not as bad as it used to be but it is still really annoying (there are other issues like god-rays etc but not too bad any more).
3. Tight area of focus - you can't focus on things off-centre by just moving your eyes, you need to move your head to bring the area of interest into the centre of your vision (an issue of the lenses in the headset). (This moving your head not your eyes doesn't suit me, doesn't seem to bother others.)
4. STUFF - want to use the galaxy map? Want to type in the comms panel? Well get used to finding work-rounds as E D doesn't do these well in VR.
5. Other Stuff - want to drink a coffee, have a beer, say bye to the wife as she leaves with the kids, use a 3rd party tool? Have fun with that.
6. Glasses - if you need specs then be prepared for issues.
Finally - and the decider that made me sell-on my Rift - you have a box strapped to your face. I found this just the worst experience and could not get used to it.
So that's just me, many MANY other people just love VR - maybe you are one of them - only one way to find out.
