Here's some of the things I've been drooling over lately.
I've been considering getting a film scanner so I can digitize all our old 35mm negatives and we could then go around to our parents and get copies of old family pictures. The best product at the moment to do a project like this seems to be the Minolta DiMage Scan Elite 5400. You need at least 4000dpi so there's a few scanners on the market that don't cost the earth and would do the job. Lots of talk up on photo.net.
All those photographs are going to take a lot of space. I really like the idea of getting an external RAID 5 storage system. One of the best options appears to be the Fibrenetix ZD-7630-EXT-FW. It's firewire based so it would be easy to move it between computers. They have 3, 4 and 6 bay systems. With large IDE drives now, it shouldn't be unrealistic to get 1 Terrabyte of safe storage.
With all that disk space, it would be tempting to embark on building a digitial music collection. I don't believe in lossy compression like MP3 but WAV files are still too big. A good solution appears to be FLAC, a lossless compression codec that will reduce a WAV file by around 50%.
