DAZ are working on their filesize problem. But they seem to be doing the geekish sin of entering the data manually. I've had better downloads with Mozilla Firefox than with Opera, but the Opera problem may be quite version-specific. The whole download accelerator issue depends on which side of the fence you're on. The sites don't like them, and they have some reasons not to. The customers do, and they have other reasons. As a customer, I think too many items come in too big a lump to download without some sort of download manager. The download-sites don't have to allow download managers for them to ease that problem.
