I use HxD (http://mh-nexus.de/en/hxd/); http://mh-nexus.de/en/hxd/); it's freeware and doesn't suck. (Previously I used XVI32 (http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.h...) and frhed (http://frhed.sourceforge.net/en/ http://frhed.sourceforge.net/en/), which are both usable. They both have somewhat non-standard UI though.
