Need some good 5.25 floppies for my IIe

I recommend getting them from RetroFloppy who are especially dedicated to the Apple II community.

Good floppy disks for an Apple are getting rare.  $30 for 10 trusted good ones is not out of line.  Your other options are to buy used disks from ebay etc, which may or may not be good, may have mold to spread to good disks and will almost certainly cause you to clean the drive heads frequently in the testing process and/or wonder if the drive is failing.  I'm not endorsing the vendor because I have no experience with them, but I think the price is fair.  Your other best option is to buy used disks in bulk of ebay etc and run the risks stated above.

Eventually you may want to move to modern solid state disk emulators for reliablilty and cost effectiveness.  But there is nothing like the sound of a Disk ][ booting to soothe the soul.   I like the FloppyEmu or W-drive as good lower cost options.  I have lots of different disk emulators, but I use those two most.  You can find many discussions here about the  "best" disk emulator.  All will handle the basic 5.25" floppy file formats well.  The primary variables seem to be availability, cost, and abilty to emulate 800k 3.5" drives or smart port hard disks as well. 

Well, it's only $16 for 10 from RetroFloppy - but the shipping charge seems a little high. I went ahead and bought some anyway since the newest ones I have around here were purchased in 1987. I've resigned myself to frequent head cleaning as I slowly copy files over to my Dan II card flash drives. As was pointed out above - there really isn't anything like the sound of an old Apple Floppy Drive.

Thanks for the pointer; I had not stumbled over RetroFloppy before this.

Random sample of 1 disk from the (sealed) box of 10 I got worked perfectly. Formatted, copied a volume on to it and booted from it.
