Most people would agree "better" means more resolution, dynamic range and DMax. If you mean "affordable", then read no further.
For 4x5 and smaller, you would look at Imacon, Scitex (flat bed) or a drum scanner. For medium format and smaller, a Nikon LS-9000 is an option. A new Imacon is in the $20K class. You can find an used Scitex flatbed for about $12K. The Nikon, if you can find one, is about $2300 with an optional (but necessary) glass holder.
