I am going to suggest you skip Harmony Remotes. My 900 just died on me after only 4 months of careful use. Previously had two 890's die as well. Both crash and go to white screen.
I just made a thread about this, seems other people are not thrilled with Harmony either. It is a shame, because when the remotes work, they work fantastic. But shelling out a few hundred dollars every 18 months for a new remote is insane, so after my 4th Harmony dies (the replacement they will ship for current 900), which I expect to happen a few days after the warranty expires, I am going to get another brand.
