Yeah, I've gotten a bunch of oranges early-on and it's nice that they can last awhile on Normal. In comparison, today I've gotten some of the orange weapons I was looking for on early farm attempts. On my third attempt while farming Bnk3r for a couple of items, I went to the red chest under the waterfall and got an OP8 Badaboom which was a weapon I was also looking for. Then on my third attempt for a White Death, Gettle dropped one but it was only an OP6, better keep going then.

Thunderball Fists and KerBlaster were my first oranges, but the most useful was the Hornet. I farmed one from Knuckledragger with each new character. You don't start finding corrosive weapons until the early teen levels so even a levelless Hornet lasts a good while.
