The post above is from the site, for what it's worth. Grains of salt are often handy to have around in these cases. Note that their own site lets you know they're down ~4 hours a year. Not amazing, not bad.
Standard wisdom is to register your domain at one place and host at another, so, if you did that, I don't see much of a downside to trying them out, but I'd use them a while before deciding to depend upon them.
I use a different, similarly inexpensive hosting company. You get what you pay for. Mine's great for offsite storage and hosting pics/files I use with MR, but I likely wouldn't host a commercial site with them. It all depends on your needs.
Caveat emptor.
