Is it worth getting? I've seen them on eBay for $100, I the update worth it or just stay with what i have, 3.0?

I second that.. What is the difference between 3.0 and 4.0? Is it worth it?

It sort of unlocks some of the features and does away w/ the legal speak when you first turn it on. Although my still does that occasionally. Oh yeah, the numbers for the clock are bigger.
