A good weight to start with the bench press?

So I'm going to start using the gym after working out at home for about 2 years. I am 6'3 and around 180 lbs. I can do about 15-16 chin ups. What would be a good weigth to start off with the bench press?

And no I don't want to go over to bodybuilder forums I've seen posts there and those guys are just aholes.
