I think it is an okay deal. Quick research shows you can get a new one with similar specs in the $1000 range. NRS seems to sell their new boards at the end of each season for less than $800.
Hala makes good stuff. As an 11' long, 6" board, it will work well for a lot of different things. If carrying yourself and your kid(s), your kids will quickly outgrow it. For one person and a small amount of personal gear it will be great for Ruby HT.
