it was actually a question from last year MrsG..... In the end we bought some black builders ones from Travis Perkins (so far, so good, if i can stop OH running off with them for construction projects). I also punched holes in the old ones and knotted rope through to make handles. No good for really heavy stuff, but works as a weed bucket
I have a load inside the house that i use for laundry, and they are still fine - so i think you are right, its the UV that makes them brittle.
