A cheaper way for him to get started is to use his Super Serial Card with ADTPro (https://adtpro.com). ADTPro can be bootstrapped onto the Apple using just a null modem cable ($5-10) connected to his PC and a couple of console commands. ADTPro can then transfer disk images from the PC and write them to floppy disks. Even if he also has to buy a USB serial adapter ($10) and floppy disks, it will be cheaper than buying a SD floppy emulator like the BMOW FloppyEMU ($109+).
I agree that is cheaper, but it is also more painful and slower. If you want to try out 100 different disk images, imagine writing those to 100 floppies (even if you overwrite and only purchase 10 floppies -- still a lot of time)
I don’t disagree, but there’s something magic about using old floppy drives. Even if you were a bit too young to have used them yourself, you may enjoy the experience. I think it’s worth trying even if you end up buying a floppy emulator later.
