Just to add my tuppence worth, i really like both Dust devil and Hardware, but i always end up watching Hardware much more often because i find it a really entertaining film, with some great visuals. Watched it when it first hit VHS and so many times since.
Helps that the central female is pretty hot.

Also has music from Motorhead, PIL and Ministry and features a brief appearance by the singer from Fields of the Nephilim.
