I still use v3 (no way was I paying again for v4 for an app I'd used less than a year), and I like it a lot, but I really need something more current. I'd consider upgrading to the Lite version of v5, as all I need is the ability to resume downloads on my constantly interrupted connection. But good heavens, the "lite" version costs almost the same as the full version--who the heck would pay for that?! If the Lite version were, say, $12.95, that might be worth it. Otherwise I'll look elsewhere.
