I had a similar problem a few years ago with the Perfection V200, using the epkowa driver. In my case the utility I first used (can't remember what, maybe scanimage) only offered me either 300 or some huge one. That was before I was on this list and I took the easy way out, used iscan which gave a good range of resolutions. So it seems to be a common issue.
