This depends what your usage of the screen will be. For most people an LCD screen will be the best screen, they are also quite cheap now compared with CRT monitors.

LCD screens save a heap of space and are light and easy to handle. Some people doing certain graphics work might prefer the colour range that CRT monitors display. Some LCDs like the Samsung 226BW offer quite a large viewing area of 22 inches, this is handy if you like to have lots of windows open.

If you are going to be doing a lot of gaming then you will need a dedicated graphics card. Basically dedicated graphics cards take over the work of handling the output of graphics to the screen and can perform this better that the computers processor can. With a high end graphics card you can increase the resolution and quality settings of the game.

Inkjet printers seem to be the most popular for home use. They work by producing dots tinier than the end of a single human hair.

The laser printer is slightly more expensive, but the ink cartridge will last for ages longer than the inkjet printer cartridge. The ink will not run if water is spilled on it. Laser printers print very quickly and are the choice for most small businesses.
