We've been with volumedrive for about 1.5-2 years, we jumped ship to dacentec.com recently. For similar reasons, faecesty support, faecesty admin control panel, faecesty random outages(excuse my language but its 100% true).
We switched to datacentec because rent to own, for us means paying 50.00 a month a year from now once we own our rack. On Volumedrive for our similarly performing setup with intel E3's it was costing us around 120.00
So when my L5520 rack is paid off a year form now and if I don't have any hardware failures, I'll be paying less than some of you renting VM's :D.
(1X) Quad Core E3-1230 (4 logical cores, 8 hyperthread cores)
2 X 1 TB harddrives
(2x) Quad Core L5520 (8 logical cores, 16 hyperthreaded cores)
2 x 128gb Crucial M4 SSD Hard Drives (Mirrored in raid1)
1 x 1TB Storage disk (for backups)
12 Month Rent to Own
Also VolumeDrives network Speeds is garbage, heres a benchmark I ran last week comparing the two hosts while I still own both servers. VD is wayyyyy oversold hence the horrible speeds on a "1GBPS port"

To run this script on your server you can get it here:
(ignore iospeeds for my result I was doing some softraid rebuilding while I did this testing).
Remember when your rent/lease a server you are renting the network, so always check speeds, always check traceroutes. Any server host that is primarily cogent could mean trouble especially if you don't shape your dns routing through something like cloudflare. Cogent only networks have a ton of hops and sometimes poor speed for, dacentec is a 60-40 split, and has a really solid network for what you pay.
Dispute via paypal, youll get your money back. Even if you lose the money volumedrive isn't worth the hassle of having as a host. We get lots of random downtime with them, which is why we switched.
As for the other hosts:
I have no direct experience with datashack or linode, but people seem to say they are decent. Also rackspace is great, but current "cloud pricing" is ridiculous when compared to budget dedi's. Also hostgator is also good for VM's, but ridiculously overpriced (partially because they are managed servers), I do have a client running on a small vm though on hostgator and they are very reliable/have great support.
Hope this helps!
