BlueHost.com Rocks! Just pay $96 for whole year and new sign-ups get a life time domain for FREE what you need more
i duuno about the best but speaking from experiemce i use hostmonster for two sites and have never had a single issue. A small bit of down time but they notified me about it when it was due to happen and wasnt very long
I say, you want reliable hosting... Get your own server We've got our own and it is great and you can host other people's on there as well and charge them for it.
For reliable shared hosting, Dreamhost.com is the way to go. If you need anything more than that (VPS or dedi), I _cannot_ say enough about WDServers.com
*for all of you guys who said blue host, if your looking for simplicity then I would'nt choose that their signup is so complicated it says 6.95/month on their main page but it ends up being $95 right when your about to confirm the order Any host that uses Cpanel is good I would personally go with hostican.com because I have a 50% off coupon they seem very professional
Me, I'm using Hostgator. Got some minor 'pinch' whenever I got some 'kick' in traffic but solve this when I utilize caching in my site.
I'm sold on Simple Helix. They are the only webhost I've tried so far that can handle Magento with ease. Half the other hosts I tried put our account on hold simply for loading a Magento site a couple times during development. Check em out.
