Has anyone used any of these tour companies in Hanoi?

I found a reasonably priced cruise tour to halong bay through this company named Indochina Legend Travel, but I am not sure if they are legitamate?

I believe they also go by several other names/sites:

Indochina Legend Co.,Ltd

www.HalongTravelGuide.com

http://www.toursvietnam.net http://www.tourshalong.com

http://www.halongtravelguide.com/

I want to see if anyone has used them and their experience?

Thanks,
