If you read text all day, get one with a Shadow mask tube. If you play games/work with graphics and whatnot, get one with a Sony Trinitron tube. Reasons behind this are that shadow mask tubes display text really sharp (depending on the monitor) while Trinitron tubes display colors with radiance. Be forewarned though, a lot of Sony monitors have geometry issues.. makes the picture look like it's swayed to one side, and no controls are available to fix it. I've had very bad experiences with busting an RMA to Sony..
