What was I thinking?

What was I thinking? I thought I had a great plan. Claire (7) has been asking for a Nintendo DS Lite for awhile now. I explained that they are pricey and not something you just buy for fun. She should put it on her Christmas list and see what happens. Well, I found a great deal - $88 at Target last October. I bought one and hid it until Christmas. Then I had to think of something equally as great for Lilly (4). I came across a camcorder by Crayola at Aldi and thought it would be perfect. What was I thinking? Lilly thought the camcorder was cool - for about 10 seconds. Until she saw her sister's pink DS. Then she was MAD! How could I get Claire something so cool and not get one for her. I thought she was too young. I thought she wouldn't be able to play the games. I thought it was too expensive of a toy for a 4 year old. What was I thinking?
Now it seems that everywere we go all of the kids are playing with a DS. I know that is what I used to tell my mom - "Everyone has one except for me." But in this case it seems to be true.

Now for the point of this post. I need to find a DS. Cheap. Lilly has put one thing and only one thing on her birthday list. You guessed it - A Nintendo DS Lite. I don't want to spend the big money on a new one. A used one is just fine. Any color will do. I can buy a skin off of ebay with Disney Princesses on it to make it girly. Do any of you out there have a kid who doesn't use theirs anymore? Maybe you upgraded to a DSi? Can you help me make Lilly's day? I am looking to spend around $50. Please let me know if you can save the day and put a smile on this little girl's face.
