My girlfriend for a late birthday present got me Actraiser and Yoshi's Island..
Squee
Yoshi's Island is my favorite video game. I own two copies, even.
Also, $30 for a GBA SP is about average, but it's not that he paid $30 for the system, it's that he paid $30 for the SP, and got a huge game lot that would have cost well over $100 if bought separately. This is without even going into the fact that 99% of the actual games are good-great. I would LOVE to get GBA Final Fantasy 5+6 if it only cost me $30.
