Chris,
Congrats on your first! Watch closely, they grow up REAL fast... mine was born what seems like just 3 or 4 years ago, and already off to college next year.
For my favorites, it would have to be either Melissa's kitchen knife (#26) or the H2 Hunter (#80). I can't decide between them. They both beg to be picked up and used - which is what attracts me to a knife.
If lightning strikes and you pick this entry (never happens!) I'd love a copy of the Scale Release Auto DVD.
