ClubHoUno - Welcome to the stringing machines forum, I see you often posting your insights in the strings section.
You are in the right forum, these people here offer great advice and they don't bite.
I would say go with an electronic constant pull unit model. The crank machines people have suggested are good machines but you were spoiled using a Babolat Star 5. Will you be able to go back turning a crank as opposed to pushing a button?
One additional note: Some of these machine listed might not be available in your country.
