Query: Disappointed! Out of focus slides and PAINFULLY slow scan times!

I recently purchased the ScanMaker i800 to scan about 1,000 family slides from the 60s and 70s. I thought I could tackle the task at hand easily by scanning 12 slides at a time. Well, just about every slide I scanned comes out extremely soft and way out of focus.I'm not sure if it's a driver thing or what but the scans came out a little better on a PC than they do on my Mac G4 running OS X 10.4. Each slide required extensive sharpening--to the point where they all look over sharpened. Prescans looked acceptable, but final scans looked horrible. I also tried to scan a few prints, but they look pretty rough as well.I've spent countless hours adjusting the settings in hopes to find a combination that worked well for me, but I just couldn't seem to get it right. This is my first scanner and I'm very disappointed. The product looks well built and all the software seems to function well, just not on my Mac :-(
