the company you mention, so I can't comment on their service.
What I can do however, is advise caution when considering registering a domain with any company which offers unusually low prices. I have clients who have encountered all kinds of problems when subsequently attempting to move the domain from such companies to a new web host. They've experienced long delays, high transfer fees, and all kinds of obstacles being put in their way. Some companies can't be contacted by phone or fax, and they don't publish a physical address on their sites, so you have a major problem if things go wrong.
I repeat - I have no knowledge of this company, and I am not suggesting that they fall into the category I've just described, but please check carefully before registering a domian name with any company.
1. Make sure you have a telephone/fax number (at least) or an address for the company.
2. Ensure that you are aware of any fees for transferring domain names or amending nameserver details.
3. Make sure that the company will send you a document confirming that the domain name is registered to you. Some companies don't do this, and subseqently it can be difficult to prove that you registered the name at all.
