The first thing to consider is whether to go with CRT or LCD. If you are looking for a basic inexpensive model, a CRT would be the best choice. If your are short on space, you should consider a flat-panel LCD (liquid crystal display). The screen is very thin, which means you can get a larger screen in a small space.
They look sleek and fashionable, and for image quality, a flat-panel cannot be beat. However, the LCD screens are more expensive than the CRT, so you will have to decide which suits your style and budget the best.
