Some basic questions regarding the Epson scanner

1. at this price point, why is there no transparency holder for 2 1/4 slides---I understand one can separate the holder from the tranny & using the existing transparency holder provided for this sized film but ............

2. what are your suggestions for scanning 5x7BW negs on this scanner

3. is the Silver Fast scanning program which is a demo for 30 odd days on a new scanner purchase a worthy purchase after the demo program has run its course? Again at this price point, the Silver Fast program should be a "purchased" item when the scanner is purchased rather than a demo

Please enlighten

thank you
