Click either photo to go to the page with a slide show of others by the same manufacturer, and you can get to their several other pages of wheelbarrows for particular trades.
This first one is elegant and pretty. Not as big and strong as I'm used to, but very attractive:
I think, but I'm not positive, that this one has a single handle. That it stands on two feet and two wheels, but can be pulled with one handle.
I suppose one would need to be a huge company to order any, but it's nice to see what exists in the world.
