I was thinking more along the lines of using a db for a forum, if it's only for a wordpress site then most hosts should be able to handle that.
Bluehost seem ok, Mickey has an account with them for Betcult and it also hosts Gav's escbet site, the control panel is pretty simple to use too, Mickey was using it for Joomla without a problem and Gav uses wordpress so it could be the answer for you, and it's cheap.
