Yeah, those 19" and 22" screens look about perfect really. Scart input (aka S-Video), decent to verging upon obscene screen size and all the other wonderful bits and bobs you need.
There are other things to look for in screens, response time, brightness, colour range, contrast etc. However the manufacturer specs are often misleading and sometimes just flat out lies. The only way to tell for sure is to find one of the half dozen sites that do high quality testing of LCD screens and hope they have a review of the pannel in question. Which is unlikely.
Don't expect the colours to be spot on (you have to pay a fortune for that in LCDs) but other than that either should be fine.
