I would have to recommend
www.aplushosting.com I've used them for about 3-4 years and they are by far the most reliable of the 6 or 7 hosts I've used in the past 3 years.
They have every bell and whistle you could imagine. With great support for high traffic, ecommerce and heavy database driven sites. (This really isn't the hosting company for a small startup website, but absolutely amazing for anyone wanting to build a larger online business)
One of the most notable features has been their tech support. Response time. And they've upgraded my server 3 times in 3 years. (Couldn't ask for more than that.)
