In Three Horns Valley, go to the hideout where you fight the Bad Maw boss. Kill him, and pick up the Eridium he drops. Then, enter the Bloodshot Stronghold, and choose the "Save and Quit" option. Continue the game, return to Three Horns Valley, and kill Bad Maw again to get more Eridium. Repeat this as many times as you like.

found it on IGN. doesn't sound like cheating since many bosses respawn anyways. it's like taking advantage more so. but i do agree with not cheating on a first playthrough, but I'm raping this guy continually if this works.
Yeah, I found a fucking amazing corrosive SMG earlier. It's awesome. Michael Mamaril gave me a revolver (Non-Elemental) that does 725 Damage, is ridiculously accurate and has a great fire rate. Got a shit-ton of great weapons on the mission where you destroy the bunker, too.
wow, was just going to update about getting an awesome revolver from Michael ^^^^. Only does 72 dmg, but that's insane for me right now. super accurate as well, no recoil. the only non-elemental I ave right now. Wish I would have been a siren instead.
