I came into this thread thinking I would be the only person to say 'I wouldn't'... I got to admit I was quite surprised.

Put me down also as someone who wouldn't take collecting back up. Now that I know how expensive the hobby can be, especially since I would be tracking down past toys, I'd rather save my cash. I have two kids aged 4 and 7 that are dependent on me and it would be irresponsible parenting to spend money on building a collection from scratch. I'd rather spend that money on giving them an education.
