I'm going to go against the grain here (ouch!) and recommend a very common developer that hasn't been mentioned: D-76. Rate the film at 1200-1600 and use it full strength, fresh, unreplenished, one shot, discard after use. Develop for the times Ilford gives for the film rated at 3200. Being a solvent developer, grain is held to a minimum. I've used this for years and consistently get excellent results. I might be wrong, but I would guess that in general it would be more commonly available world wide than almost any other developer.
