Me too, in a way at least. What is available for purchase, and the price always are factors, but public domain status makes a difference too. A PD book will almost always beat out a non-PD book simply because I can share it. The last bunch of GA books I bought were Hopalong Cassidy #66-67, Love Problems and Advice Illustrated #15, Super Duck #42, and Young Romance #49. I bought them in a store, and all were five dollars or less. However, a few years ago, I'd have probably passed all or most of them up, opting for some of the Atlas books they had, Captain Marvel Adventures #83, or a 1950s Superboy or Adventure Comics issue. I knew I couldn't share the Atlas or DC books, and CMA was already scanned, so I went for the low hanging fruit. (Although I may still go back for Cap just because I want it.)
I don't think any of the books I bought have been scanned, so I can't wait to do that. I started scanning Hopalong Cassidy #66 a week and a half ago, but right after I did, my computer crashed. I didn't have time to upload it, or for Carbonite to back it up, but I have a new hard drive coming today. Hopefully I can get my computer set up again soon to either rescan it, or recover it from the old drive.
