Saw this in a thread at cheapassgamer.com - Target is about to send out it's Xmas catalog, which shows that the Nintendo DS is 100$ new. There is much discussion as to if this is a misprint - so YMMV. Click the Page index section and check page 56.

Also noticing that the feeding frenzy that is ebay right now has bid the Nintendogs Best friends edition (the one that only comes with the teal and pink Nintendogs bundles) is being bid up into the 65$ range - so for any of you cheapasses like myself you can get the bundle, ebay the game, and net a ds for around 85$.
