Anyone know where to get one at a reasonable price?

no but i still remember making one in school for a sewing project it was awesome easy too

Target has them. Not sure about the price.

i know i have seen them at one time in WM-like the character ones etc. Look in the section where theyve got furniture, lamps etc. I got my kids two in Target, theyve got nicer looking ones, we got a red one and white with pink dots. they were like 18 dollars ea-the fabric is like a canvas and they are filled with i think styrafoam peanuts. ours havent torn and they look great. one thing i noticed is they are starting to lose some size as the peanuts get squished down, but there is a zipper on the side im going to open and fill it up a bit at some point.
