Starting my Borderlands 1 Farming Journey

Hi, all!

I've been playing the Borderlands series since I was in elementary school when Borderlands 1 came out. I have played every game since, and put TONS of hours into all of them. (Casually playing the story and farming for end gear loot and bosses)

I have decided I want to hunt rarer weapons, and collect all of them. I will start with my level 69 Siren in Borderlands 1. I am currently hunting a decent Spectre COM so I can start farming Crawmerax. Maybe even some links to builds that I could use because I will be going almost blind.

Is there a list somewhere with near crazy odd drops that I can sink 100s of hours into the game just to get? I'd like to start with 1, and maybe go into 2/3 once I complete it.

Thanks!
