I'd rather have Edwards than Orton at this point and here is why:
with Edwards, Henne has no excuses not to succeed, so he either gets it done and we are in the playoffs or he doesnt and we draft a QB in round 1 next year and OMG WEAPONGASM! Rookie QB has two top WR's to throw to, one of the best slot guys in the league, a good pass catching back and if Charles Clay blooms the way we all want him to a young, solid TE. Oh yeah, we also should have a pretty good line to protect the new QB and a Defense that should always keep us in games. So, yes, he's a rookie, but he's flush with help and is in a situation created for his success. Think Joe Flacco in Baltimore. Drafted #18, not expected to start right away, gets put in the lineup week 1 and leads the team to the playoffs in each of his first 3 seasons.
If you invest at all in Orton (either via traded assets or on a FA contact if he is cut), this scenario becomes unlikely, especially if you send a draft pick for him (let's say it's a 4th, and he doesn't work out, then we have to spend an additional 2012 pick on a QB, meaning we spent a 1st and a 4th to find our 2012 starting QB as opposed to the first scenario when we only spend the 1st and the 4th is free to be used for another position).
Go get Braylon. Maybe we'll have the Killer B's on offense this time...Brandon, Braylon, Bush, Bess....
