i don't even know what you would get for $70 - I think it would break on you. I think a better comparison may be a $300 bat vs $700.
I spent $300 on my bat. my team mate just spent $700. He got it custom made - and requested that the meat be put down low in the bat because thats where he hits the ball. I don't think he could have found a bat off the rack to meet his requirements.
As far as I am concerned my $300 bat is as good if not better than anyone's on the team. When guys borrow it to hit out catches to the team I always catch them admiring the bat afterwards.
