Generally, you use this forum for getting reviews on hosts. They would be real life reviews with the incentive of sharing experiences. Sometimes you may get a few opinions when asked but it would be best to search for people actually using the services you are asking opinion about.
I have heard some good things about them, though personally I would be weary of hosts which oversell to such an extent. Lypha (1TB) type accounts just don't happen on most servers. An average server has a 160gb har drive, larger hosts can afford better though if you actually intend to use a lot then I would read their TOS. You might find a catch in there.
I know, for example, that eBay unlimited reseller hosts limit your webspace to HTML, graphic and flash files generally to avoid people using their $5 unlimited reseller to backup their hard drive or store large files. A good host will let you use your webspace how you want with as few limitations as possible. With overselling to such a degree they may not.
This is not a rant, as far as I know they're good, but it may be worth reading their TOS and not just accepting them blindly.
