I bought my girlfriend an SP over the weekend at a flea market for $20. It came with the first teenage mutant ninja turtle game on gba and a charger. I was really reluctant at first to buy (my maximum price was $15) but I caved in once I realized it came with a game. I didn't even realize it was an AGS101 until after I bought it, it definitely justified my decision more.
We went to a local game shop in SC (Video Game Cavern) and picked up:
Donkey Kong Country (GBC) -$5
Tetris (GB) - $2
Yugioh Dark Duel Stories (GBC) - $3
I ended up picking up Tech Dech for GBC. I remember playing that via emu when it was first released and I liked it. Not so much now though haha.
Anyways we also went to this new used media store opening in many places called 2nd Hand Charles. There we picked up Lil and Stitch for GBA. I totally forgot that game was a run and gun. Pretty damn cool game surprisingly.
