A few points to add;

1. Typical consumer grade LCD monitors are only capable of producing an 82% color gamut....better models (more expensive) will give you up to over 120% color gamut.
2. If you are truly concerned about color fidelity...remember to consider the cost of a hardware calibration device into your budget
3. Be wary of the "high gloss" LCD screens...they can be difficult to accurately calibrate.
   4) You may have some difficulty being able to find a 4:3 aspect ratio model out there...unless it is old stock....

In youth, we learn....with age, we understand.
