I almost forgot to tell you about my last pony purchase!
Hashbro ~Hashbro (https://www.deviantart.com/hashbro) models ponies and sends them to Shapeways, so they can 3D print it for you.
His models, although only a few at the moment, are really well done!
Just wanted to inform you all about this, because I think it's one of the cheapest ways to get an awesome show-accurate pony model.
You can find more information on his site at http://printingponies.jimdo.com/
And here's a pic of my 3D models, hanging out in Twilight's library. http://fav.me/d514y82
I'm really happy with them, so if you want some as well, and have a bit of money to spare, grab them while you can!
