Insignify is a brilliant, very low cost hosting opportunity. I have used this hosting site for at least 2 of my websites, and I find their customer support outstanding. I'd also like to mention that the up-time on the website is outstanding, and was even more improved when I beta tested one of their new servers.
I've been using Foundation Hosting for over 2 years and they have never let me down. Their up-time is as good as it gets and their support is absolutely amazing. For my duration at FH I have used Application Hosting and more recently I have also started to use Plesk for my sites. If I had any issues, I was able to get help and support within a few hours. Overall, I would highly recommend to a friend and I have done so!
