Require your help in choosing a good vps host

I require:
120 gbs of HD, 2500 GB of bandwidth, 2 gbs of ram. Opencart support
+ 24/7 customer support.
Found these ones: 1) ; 2) ; 3)
What can you say about these web hosting providers?
Any info on the quality of their web hosting services and their server stability?
In my opinion there is not better host then with the same price I mean.
I have been with many hosts too and had several really bad experiences but this one makes me feel as if I am a welcomed customer or even a real person.
