Hi Guys,
I have been with RocketColo.net for a month and some change, and they have been nothing but great!! So, here's the rundown:

Network: Great, some lag issues at times, but nothing major.(Level3, Cogent, Epik)
Hardware: Good for the price, I have had no issues with running my server
Based: Orlando, FL(Nice Location)
Build your own custom server > I used this and I even got a $20 off!
Ensim Pro 100 great deal for $30!
Support: Best! Live support is great, they always help me with issues, even some that they shouldn't!

Overall, I have had good experience with them, I recommend them. I will give a 3 month update soon
