I love Strangers gundown and No room to die. Both efforts are flawed but effective and stylish. You can see my reviews for both these films at fistfulofpasta.com. (shameless plug lol)
Outside of these two I'm not really into his other westerns, Django Kill was too bizarre for me, Killer Kid (writing credits) was ok but nothing special, Django the last killer (producer) could've been alot better than it was, but its nice to See George Eastman in a lead role playing a badass mexican protagonist.
