Hawk Host web hosting has been hosting my wordpress blog for over 4 years now and I haven't had any problem with them.
Customer service is fast and really great. I highly recommend hawk host for wordpress or any other websites.
You can also look in the advertising sections of
http://webmasterbabble.com and
http://webhostingtalk.com and other webmaster and internet marketing forums for good web hosts.
And you can also get reviews from other members on those forums.
