Service Manuals/Literature

Along with a scan tool, we are looking to jump into some service literature...

Is Alldata still the best bang for the buck to cover the light and medium duties? I priced out Alldata and Mitchell.

Heavy truck info would be nice, but I can't justify the $4k add on price from Mitchell.

Alldata was the standard $1,500, Mitchell without the HD was $1,800.

Any others out there or are these still the standard?

Thanks!
