Impossible to answer without knowing the name. Don't post the name though, or someone else could grab it. Check the other domain extensions... if they're all gone it could be a good buy, if they're all still available, probably not a good buy.
My motto is that if you're not sure, it's usually not worth getting. When you see a good domain you KNOW it's good and you won't hesitate. Buying domains and blowing your $$$ is too easy, you need to be selective and buy the best quality within your budget.
