rockbox will do it on any of these supported players:
Code:
# Apple: 1st through 5.5th generation iPod, iPod Mini and 1st generation iPod Nano
(not the Shuffle, 2nd/3rd gen Nano, Classic or Touch)
# Archos: Jukebox 5000, 6000, Studio, Recorder, FM Recorder, Recorder V2 and Ondio
# Cowon: iAudio X5, X5V, X5L, M5 and M5L
# iriver: H100, H300 and H10 series
# SanDisk: Sansa e200 and e200R series
# Toshiba: Gigabeat X and F series (not the S series)
I just tested it on my gigabeat, resumes every time however you stop playback.
not sure if any of those are (cheap) flash, but with rockbox they will all work the same in terms of UI/OS
