I have 3 domains with Ripplehost. All personal pages of family/friends I am administrating. I recomend it to anyone that is just setting up a page to play with and maybe do some small picture posting and blogging. My page is ripplehost too. You can check out the speed from the link in my sig.
There have been a few outages/burps in service that I have noticed. Nothing major. Plus the support from ripplehost is non-exhistant. You basically buy the account and are left to other users in the forum to answer any questions. If you feel like a self starter/self learner that wants a cheap account to play around with, go with ripplehost. If you need a little more handholding or have a site that needs 24/7 uptime and security, I would go with addaction or get a bunch of people together and go with Datahorn.
For the price per year what others charge per month, what else can you really expect?
