So I want to get a network hard drive to do automated Time Machine backups. I have an external HD that I've been using, but only do it every few days when I remember to plug it in. Which means I can lose a few days data if something goes wrong, which I did last week. So in my research I've found three solutions that will work for me. But I just can't decide which to get, and would love suggestions. 1) Get the Airport Extreme, and connect a spare 250GB HD I have laying around doing nothing. This is the cheapest solution. I have an Airport Express now, and love it, but want the USB HD feature of the Extreme. This is the lowest cost solution. 2) So I'm thinking, as long as I spend the $129 for a refurb Extreme, why not spend $50 more and get the refurb 1TB Time Capsule. It's basically the Extreme with a 1TB HD build in. 3) Then I think, as long as I spend $179 on a Time Capsule, why not spend $37 more and get the LaCie Wireless Space, which does everything the Time Capsule does (minus the dual band), but would also work as a media server for my PS3. So the jump from number 1 to number 2 isn't very expensive. And the jump from number 2 to 3 isn't very expensive. But when I look at the cost difference between 1 and 3 it's almost $100. I just can't decide which to get. Anyone care to comment?
