Just thought I would let you all know about my experience with the Indivision 1200.
Installation was a breeze. Initially I was worried as my rev 1d board has a "green wire" fix that runs along side the gayle and lisa chips but thankfully the hot glue dots do not foul the connector - but I'm sure it wouldn't have been a major issue to resolve if they did.
It clicked on easily, I'd say with the roughly the same amount of force as installing a tight dimm memory module. Although I didn't, I would recommend putting the board on a flat soft surface as I noticed some flexing
I did use a little Isopropyl Alcohol (IPA, Rubbing alcohol) on a cotton bud around the pins on the lisa chip before fitting, and have not experienced any problems with picture quality - which is EXCELLENT!
To be honest, after preordering I initially regretted it but I am so glad I didn't cancel it - it's really made my week!
After tea I'm going to try updating and tinkering with the new settings - happy happy joy joy.
