speaking of monitors - I've recently moved house and found a new monitor still boxed in the house - its not a flat screen but it is free to a good home if anyone wants it
What's the native resolution of the two LCDs, and what will you be using it for? Remember 19" LCD is actually 21" CRT, which is already quite big for close up work. Unless the 22" gives you more pixels, it might be too big. Though that won't be an issue if you are using it mainly for games/video.
Update: reading the links, it looks like the pixels are actually slightly smaller on the bigger screen. So my points aren't really relevant.
