I just switched to PowerVPS after doing a day of research. So far so good..but it's too early to tell. I haven't read anything bad about them and lots of good things. Prices are also very fair. The transition was ultra smooth and they were VERY responsive.
I've been with PowerVPS for the last few weeks or so. The server speed is very good, tech support is excellent, prices aren't too bad either. They have a support forum where users, techs, even the CEO posts and lots of questions can be answered there.
too bad, PowerVPS give bandwidth up to 500Gb per month already. My site averagely use 400-500Gb bandwidth per month and at spry.com I get 700Gb bandwidth
I wouldnt go near burst.net if you paid me. Most of their IP blocks are blacklisted for spam support.
