Woah.... Where do you understand that from?

My notes (I haven't tried this yet myself, but anticipate I will at some point) say the following models will all serves as screen donors to a 48, Some of them may be preferable to others on account of availability/cost, but I think they ALL work.
If there are errors (or omissions!) here, someone please chime in.

• 49G
• 39G
• 40G
• 39g+
• 39gs
• 40gs

My information is at least partly based upon this thread:
