I pay $24.95/month for their shared hosting service. They do not provide a control panel or anything "fancy". I get SSH and a MySQL instance, and that's all I need.
Last night, one of the pages hosted there got massively RT'd on twitter, Livestream, and several other social media sites, producing over 10,000 PVs within minutes and peaking at over ~2000 concurrent users online.
Not a single slowdown, no lag at all, didn't skip a beat.
I also don't recall a single downtime since I started hosting there.
Support replies within minutes, even if I'm emailing at 4 in the morning. The only thing I don't like is that you can only properly host one domain.
I assume the number of the domain names depends on the chosen web hosting service account and if you need you can ask if the web hosting service provider can provide that for you maybe for some additional fee or simple upgrade account
HE has 3 different "version" servers... that's nomenclature more often used internally as the customer doesn't necessarily have any idea which they might be on (if they are an older customer). Any new customer would be put on a "version 3" server unless they specifically requested older stuff.
The text based control panel is the same regardless of what actual server hosts your sites.
The system should automatically create any redirects for you within 24 hours... and the older method of using mod_rewrite to host alternate or sub-domains shouldn't be necessary (I haven't actually used the newer multi-domain features... I only use a he account for backup image file serving.)
The limitation of of the added domains through their system is they are not setup for email services, for that you'd need to use Google Apps or redirect addresses at your registrar.
Their $1/mo account is also a very cost effective solution for many basic web sites.
