These are the hosts that I've had 1st hand experience with:

• GreenGeeks

  My Top Pick    |    Check'em Out » 
  PRICE: $4.95/mo (3 yr term) $6.95/mo (2 yr term) 
  Admin Tool: cPanel
  
  These guys offset their carbon footprint by purchasing wind energy credits, enough to offset 300% of their consumption.  Additionally, the server I'm on is a dual quad core (8 core total) machine with tons of features out of the box:  cPanel, ssh access, service status, unlimited everything.  No nickel and diming, no upsells, no crippled cPanel, North-American based phone support.  Fast, full-featured and guilt free.  
  
  This site is now hosted with GreenGeeks.

• JustHost

  Highly Recommended      |    Check'em Out »
  PRICE: $2.95/mo (w/coupon: 50OFF)
  Admin Tool: cPanel
  
  Cheapest cpanel host around. Performance ain't bad, can't speak to service yet.

• MidPhase

  Highly Recommended     |    Check'em Out »
  PRICE: $5-8 $2.95/mo (Starter Package)
  Admin Tool: cPanel
  
  Good balance of price and service. Possibly intermittent performance, but quite fast when all is running properly.  Starter package is very limited.

• AN Hosting

  Highly Recommended     |    Check'em Out » 
  PRICE: $5/mo 
  Admin Tool: cPanel
  
  These guys were bought by MidPhase a while back, and as far as i know, are essentially rebadged MidPhase hosting.
  
  

• Crucial Paradigm

  Recommended      |    Check'em Out »
  PRICE: $6-25/mo
  Admin Tool: cPanel (for shared hosting)
  
  Servers seem uncrowded, great performance great ticket-based support, but features:price ratio is a bit weak, and these guys don't really "specialize" in Drupal.  Their overly-paranoid mod-security settings give views and other ajax functions some trouble unless you ask tech support to disable it.  One other thing worth mentioning, and it may have just been bad luck, but in under one year of service with them my server went down twice.  This was reportedly due to their upstream power providers, but left me feeling a bit unsettled.  Still, their response was very professional, and i still had an overall positive experience with them.
  

• DrupalValueHosting

  Stay Away     |    (I won't even link to these guys anymore.. please don't sign up with them)
  PRICE: $10/mo
  Admin Tool: cPanel
  
   DVH is a new hosting provider. They started out really strong but have suffered some growing pains on the support side. Blazing fast and cheap, but poor support options. I have seven unanswered support tickets over 3 months old. I still have an account with them (even though i requested cancellation over 6 months ago !).
  

• 1and1

  Not Recommended     |   Check'em Out »
  PRICE: $4-10/mo
  Admin Tool: Proprietary, clunky (but, their vps uses Plesk)
  
  Cheap. Good place to buy cheap domains. Shared hosting runs mySql on remote servers which usually = high latency, and slow load times for DB intensive apps like Drupal. Server software (PHP, apache) is often outdated. Also, their cheapest packages can't run Drupal's clean urls out of the box, don't give you ssh and php's multibyte extension isn't installed.
  

• MediaTemple

  Not Recommended     |      Check'em Out »
  PRICE: $20/mo
  Admin Tool: Proprietary, sexy, mostly intuitive
  
  I've tried the GridService, even with the add-on MySQL GridContainers (~30/month alltogether) and Drupal performance still sucks. Like 1and1, this is due to mySql DB being on a different physical box than your hosting. Faster than 1and1 shared hosting... but still far from 'fast': Proof that a sexy site and control panel do not = great hosting.
