I love my elecctric GoBig--saves my shoulder and my carpal tunnel issues. I don't often buy BOBs either, Suzanne, because they don't seem as flexible. I do have the log cabin and a couple like LeMoyne Star that I could pull parts from to use elsewhere. I do have both Cleopatra's Fan and 6" DP because it can cut so much more accurate than I can on those curves.
I think,Suzanne, if you hover your mouse over the picture of the die on the Accuquilt website it will show you the die made up. If you click to bring up the details, there usually is a space near the top that shows you a couple of ideas on use.
