I believe the previous conclusion to this conversation was, "Just get money; money will buy what we need. We don't want SINs provided by someone we don't trust."
But, don't let me influence you. You are more than welcome to lay out your Christmas lists. Personally I think it's a fascinating question because it suggests a lot about what the character wants to do next in their lives, which is very telling.
Ideas include: gear (armor, weapons, foci, formulae, magical compounds/supplies), vehicles, travel vouchers, visas, IDs, and so on. Doc could ask for access to a lab but that would require him to trust someone not to bag him. Doc remembers that DIMR and MIT&T did some research on otaku about 15 years ago (to see if their abilities were magical in nature), so presumably the DIMR has access to some sort of research facility that might be able to work on CFD and/or magically erased memories.
Katsina
Katsina already has a really good SIN that hasn't been used, so she feels okay about that. DIMR and ASPS seem like good sources of magical equipment but a lot of that is so personal (and tradition-specific) that she'd be inclined simply to enchant it for herself, given the time and resources. She hasn't seen the RV yet but when she does she will probably want one. She doesn't know where she wants to go yet but she does know that she wants to lay low until the heat from this blows over. Plus, maybe some additional downtime will allow her to recover more memories (or maybe not). She wants to run away with Ace but won't leave Sam behind until he's at least somewhat adapted to his new diet.
