Just a quick update, for those who might be interested:
The bank allowed the pending charges from the stolen card to be dropped without posting thanks to a timely report of the theft. (Thank goodness she was with our paranoid friend who shoved a phone at her and made her cancel the card asap.) No other leads have come along, so we're in full 'replace stuff mode' now. I got lucky and found a DS lite in great shape at a pawn shop, priced incorrectly at $60. Probably not the best deal I could get by a long shot, but we have a convention coming up so time was a factor. We picked up a few of the games as well, but she was carrying around some good stuff that day- it's not bad, but it's not gonna be super-cheap to rebuy. Luckily we can go game only on everything since the cases were at home.
We've replaced Big Brain Academy (this was missing beforehand), Pokemon Heartgold, Phantom Brave (PSP), Loco Roco 2, Sonic Rivals 2, Sonic Rush, Knights in the Knightmare, and Ape Escape on the Loose.
What's still gone:
Final Fantasy Dissidia
Little Big Planet
PSP-3000 in lilac (the Hanna Montana one)
Professor Layton and the Last Spectre
Sonic Rush Adventure
Harvest Moon DS
Kirby Sqeak Squad (this was actually lost by her little sister prior to this)
Super Mario 64 DS
Yoshi's Island DS
So, y'know... if anyone sees a good deal on these, let me know? I'd just post to the trade forum, but with 3 of us game-hunting I figure most things would fall through because someone else would find it before I hammered out the details. Not to mention my only trade fodder is a spare NES and two incomplete copies of Trap Gunner for the PS1.
