I'm 140ish and have recently started dead lifting about 3-4 weeks ago. So I guess you can use me as a what a beginner should start off around.
Last time I did, I did 3x10x165. I think I could have gone to about 170-175ish for 3x10 though, didn't really feel to tired/sore after those sets. I've just been taking it easy since I'm still a noob at deads. Don't want to get hurt, since I'm also not using a belt or whatever.
200 would be quite good if you're just starting out. 300+ as some have suggested is rather a lot for somebody weighing 135lbs, and it takes a while to work up to deadlifting over twice your body weight..
