After trying out lots of different VNC apps, I found this one and am very pleased with it. Its easy to set up, works very fast, and has lots of excellent, thoughtful features (ie the trackpad overlay and on-screen cursor-click locator). And judging by the devs website & forums, its quite well supported. Most other VNC apps are either free (and you can tell because they are hard to use, have a bad UI or lack features) or at least $5 (if not $10-30 and have way more features than most people would ever use). This one, for $1 at the time got it, is really nice.
