I've used Blue Host for about 10 months. I host a tutorial and arcade site with them, averaging at about 16k pageviews/day (combined). Apart from a couple of instances in the summer for me they have been reliable, and so i'd choose them again if i had to decide.
blue host is ok. i use them. though at times they have downtimes but the good thing is they inform you where the problem was and what they did to rectify it
You really should spend some time at Web Hosting Talk (webhostingtalk.com) researching hosts before signing up with anyone in particular. Research the background of each prospective company, send pre-sales inquiries and see how they are answered. And, go through each company's sites very carefully to find out exactly what you get with your plan, so you aren't let down later. Good luck with your search! Bailey
