When buying used, how much are you looking to spend? Half price of original ticket price?

The reason I'm asking is because I'm looking into getting a Choo Choo Wagon. But I'm finding that people are selling them too close to store ticket prices. At that point, I'd rather spend the extra $30-50 and buy brand new.

What are your thoughts?!!? Thanks! (I cannot start a new thread, so sorry I had to hijack this one!)
