on the amiga side, you should use UnZip - on aminet - i've used it for a couple years now with many zips from PC transfers, no problems yet.
on the PC side, use UltimateZip - it's free, and can make/unlha .lha archives as well as zips, great program. . I've transfered lha's from/to amigas and made them/unarchived them with UltimateZip no problemo. . .
