slowgo Thanks for asking this. I am in the same boat as you. I am trying to decide if I should upgrade from my three year old 520 to the 1030 since it's on sale right now. Trouble is, my 520 works great. Well great that is until I pair the 520 with my Varia. Then the battery life goes down terribly. Still trying to see if there's a way around that.

I am interested in hearing what you finally decide. Cheers.
