What's a good price for a used bluefin 6000. I thinking about getting one for 240. But then again I'm thinking about a dart for 300 new with 2 yr warenty. Which one should I get its for a 300g. Iim not spending 3 something for the super dart so its either the bluefin or normal dart. How are they on noise as well heard the both silent then heard there both loud
