I've put in 500+ and don't have a g-horn and I'm happy that there is at least 1 gun in the game that people want and can't just buy. Games aren't supposed to be all inclusive for every little thing in them. Having some rare weapons and armor is good IMO. Gives people something to strive for. The only way I would be OK with Gally being open for everyone to get would be at the end of a very very hard exotic weapon quest line.
