Actually pair.com is positively pricy compared with
http://www.ipowerweb.com/.
What you'll find, though, is that cheap hosts have no problem letting you run PHP, but they won't offer mod_perl. So yes, Perl is there. But you won't get the throughput and performance that you will if you switch languages.
The reason is that it is harder to lock down mod_perl than PHP in a shared Apache server. Which has nothing to do with anything that wassercrat(s) was complaining about.
