Thanks for your information, I probably will stick with 17" monitor for now, and will get some more power for my comp!! Cal, those sites, is it possible to order from them and they can send it to me or do I have to go there and pick it up myself? If so, I have family in Calgary and I would ask them if they would do it for me.
