Good Website Hosts

I hope this is the correct forum for this. I am currently with IxWebhosting. I have noticed that my sites have become real slow with them. Also, online, there isn't much said about them that is good. I am thinking about switching to a different host.

One problem I also noticed with their hosting, is on my wordpress sites, I can't modify the permalink structure to something nice. If I do, my website pages come up as page not found. I heard this can be a problem with some websites. I also bought a dynamic theme for wordpress, and it won't install properly with my sites.

So I want to change web hosts.

Do any of you know of good hosts, that offer at least 1 free domain registration so I can move my personal site over to the new host without registering the domain with a separate company, has a lot of data space, unlimited domain hosting, a lot of bandwith uses php 5 and apache servers, and you know that the permalink structure can be changed in wordpress. Also I have heard a lot of good things about cpanel.

I'm kind of a newb when it comes to hosting. I pretty much just went with ixwebhosting without really reading into them much. So for those of you who are pro, and know whats best for interenet marketers and those especially that use wordpress, it would be nice to have your input.

I want a host that can do everything wordpress needs to.

Also how hard is it going to be to transfer my wordpress site over to a new host? Is that difficult.
