more saw blade ??s

[Skip Albright <salbrigh@nycap.rr.com>]

I use a sawzall to dismember cars.  works well, but I use up blades 
at an alarming rate.
I have tried several brands and tooth sizes, all either break off at 
the tang or  go dull in moments.
todays batch are Bosch 14 tooth blades. I have tried "bi-metal blades 
with little difference , except on my wallet.

Any hints or favorites?

thanks
