I got my Lynx-II Mod last week and installed it this weekend. Despite my rusty soldering skills, everything worked the first time I powered it up. The improvement is amazing.
I would recommend removing the LCD ribbon cable connector before trying to solder the wires to the Lync board for the LCD. It makes it much easier. I wasted about an hour trying to do it before giving up and removing the connector. Also, a Dremmel tool works great for cutting the opening for the VGA connector.
I made a little slide show with some pictures of the upgrade process and some before and after images of the screen:

I'm very happy with this kit and had a lot of fun installing it.
