My wife has given me a holiday budget (translated: I won't nag you about this) and I'm thinking of getting a second monitor to have more Vegas real estate (I already use a TV for the external preview monitor). With an existing 17" ViewSonic CRT, a GeForce FX 5200 dual head card and Canopus ADVC10 converter, might anyone have a second to comment on whether adding a second 17" versus 19" screen, or second CRT vs. flat-panel, is preferable?
