Does buying your kid a second-hand Christmas gift put you in Scrooge territory?

I bought my daughter a second-hand present this Christmas. It's a trampoline and she LOVES it (yes, it's set up already). Part of me felt mean going the second-hand path, but after thinking about it there are many benefits:
* It only cost $80.
* It was already partially assembled. I was able to piece it together myself while the Prospector was at work. He was happy about that.
* No massive box and miles of padding, usually requiring a trip to the tip, to deal with. Ditto re Prospector being pleased.
* Buying a used item is gentler on the environment.
* We wanted a trampoline (in good condition), the sellers wanted theirs gone. Win-win.
* Rose doesn't give a toss how old or cheap it is. All she knows is she loves the things and now there's one in the back yard. 

Wheeee!

She's not yet two so I thought she may have been a bit young for a trampoline. But every time we've been somewhere with one, she climbs on up and has a ball. She also decided the low-hanging shade sail over our veggie patch (which has allowed the weeds to run rampant but come hot weather does nothing for the perkiness of my tomatoes) was a trampoline and repeatedly asked to bounce on it. Clearly, I had no choice but to try and get one for her. Not that she's spoilt, or anything.
And, yes, I admit it's kind of fun for me too. Do you want to know how high I can jump before scaring myself?
Also, it's handy when I finally do my hand washing and need to lay everything out flat.

What's your take on pre-loved gifts?
