Thank you, Scott. It looks like the best of the list you provided would be the Radaee Viewer for my purposes. I'll load it into the tablet I have, to take a look.
I don't need lots of search options for songs and can work with an alphabetic list as I build a set list or select songs from the library. I am looking at Orpheus Sheet Music Reader at this time.
http://www.orpheus-app.com/ It looks like it fits my needs but want to find out how it handles the PDF files. I am hoping for something that works like the Windows "Music Reader" software that actually changes the PDF file with any edits you do. That would make the PDF library usable with other PDF readers.
It looks like I'm back to using the Hannspree tablet. Waited almost a week for shipment of the Archos unit and finally found that it was back-ordered. Canceled that and reordered the Hannspree. Should be here by Wednesday.
