I know it's an old thread but here's some input for future wheelbarrow/garden cart owners.
I've abused many wheelbarrows, steel, plastic, fiberglass, wood handles, steel handles. The steel wheelbarrows will rust. The plastic will break. The fiberglass, well I broke it somehow too. I've used duct tape and kept it going for the last couple years, but the steel handles are starting to show their age. I put a never go flat tire on it a year or two ago and like those. I'll take it off and put it on the new one I'm getting this spring. So I'm going to get a 6' cubic foot. Sure the load of gravel or soil will be heavy if you fill it up. SO don't fill it up all the way. I'd rather have one that's too large than not large enough for the lighter stuff. If I can find one, I'll get one with fiberglass handles and another fiberglass or non brittle plastic bed. I like the idea of dual wheels but the single wheel gives me more manueverability so I'll likely stay with the single wheel.
