Subject: Duplicating DFS / ADFS floppies

What's the least-painless way of duplicating both DFS and ADFS floppies?

Potentially-useful stuff I've got:

   A B+ with both ADFS and 1770 DFS ROMs in it.
   An EPROM burner.
   A floppy with a working copy of AFORM on it so I can format ADFS disks.

Possibilities seem to be:

   - Some sort of simple one-liner already built into both DFS and ADFS
     ROMs (seems unlikely).
   - Some sort of simple BASIC program to do a sector-by-sector copy
     (assuming a formatted destination disk)
   - Some sort of downloaded floppy-based utility to do the job.
   - Some sort of utility that might already be lurking on various
     welcome, utils etc. disks.
   - Some sort of ROM-based utility to do the job.

What are other people using? I suspect it's far easier for me to download a 
ROM image and burn an EPROM than it is for me to download a disk image and 
write that out (the latter involves either screwing around with xfer, or 
bouncing the image to a machine that'll both understand the image format and 
is able to write sector data correctly)

I think I've got Watford and Viglen utils disks kicking around the place, but 
I suspect that even if they do come with a duplicator, they won't be happy 
with ADFS media. The only copy of the ADFS utils disk I have is unfortunately 
trashed (and version 0.1 too and so probably full 'o bugs :-)
