Tamron 70-300mm 4-5.6 Di LD - are these any good? Has anyone had any problem with one?

My partner & I both have this lens 7 both have stopped working. I was wondering if anyone else has had problems with them. Ours were bought from different places about 6 months apart. We've had them less than 2 years so i'm exceptionally annoyed that they've stopped working.

I had one of these back with my Canon 40D, the first one I purchased was DOA and was replaced but I never had much need to use it.
