Webhosting talk is a great place to look for info on hosting.

Personally I'm happy with Hetzner:

But I think you could find cheaper (but good) alternatives if you want hosting in the US.

I used Honelive for a while and I think you should be reasonably happy with them at that price range.

However, I eventually needed an upgraded server, most importantly the ability to do an out-of-band remote reboot. I switched to Hivelocity for that.

To get the best deals on hosting, look carefully at the hosting company's website, search for announcements of sales on Webhostingtalk, and check their Twitter and other social media.

For mid-range dedicated hosting, I've been using OVH and have generally been happy with them.

It's important to note that their North American data centers are actually located in Canada although I do believe they are planning on eventually opening a data center in the US.

Webhosting talk makes my brain hurt with so much noise vs signal to sort through :-)

But I did stumble across http://serverbear.com/ which seems to have some useful information, though many of the plans they show aren't actually available (out of stock) at the providers listed...
