Thanks for the offer Mic but I think she'd kill me if I bought one of those for her - great camera but it blows our budget totally out of the water. I think the Holga/instant back camera may be the closest fit to what she's want.
At this point, I think I'm going to shift focus to her TLR interest. She liked my Rollei and was interested in something similar. Maybe that would be a good way to keep her film interest growing instead.
