What exactly is it that you like about Joy Division? All the bands mentioned are, without a doubt, fantastic and worth listening to, but almost none of them sound anything like Joy Division. They each have their own unique thing going on, much like Joy Division did.
If you're willing to go digging for some more obscure stuff, there's definitely a lot of post-punk out there worth checking out. Some of my faves include:
Young Marble Giants
The Stockholm Monsters
The Homosexuals
The Wake
Swell Maps
The Orchids
Section 25
Crispy Ambulance (Sec. 25 & Crispy Ambulance were both much more instrumental than any of the aforementioned bands, but trafficked in a similar dub-drenched deconstructed punk as JD).
It might also be worthwhile to check out the
LTM Records page. It's a label that reissues the more obscure Factory Record bands (Joy Division, and New Order's, label).
