I Need a Perfect BINDER . What should I choose?

I would like advice on choosing a binder.

My annual production on the book is about 150 k
I was thinking between:

Heidelberg Eurobind 600
Horizont BQ 270, BQ 280
Duplo DPB 500 , or
CP Bourg .

Can you help me with the selection?, or suggest another model that you value more
the budget amounts to around 25,000 euros.
Thanks

 

Hi dear,
Heidelberg Euro bind 600 is beater than other......
