I have a short- handled one and the long handled one. The circles are the same size, I think. Mine were Christmas presents purchased online.
If I'm going to do a lot of weeding, I use the long handled one. But whenever I work in the yard I carry a little tote containing my necessities- the short handled circle hoe, a trowel, plant markers and pen, gloves... you know, stuff I know I'll use a lot. Those things live in my basket all the time.
