Buying a home computer can be a bit like buying a car-it's a major purchase decision. There are many makes and models, and many people willing to give advice about what to buy and where to buy it. To make the most of your shopping experience, and sense of the variety of choices facing you, you'll want to do your homework before heading out. And, whether buying new or used, know what you want the computer to do for you and how much you can afford to spend.

• Buying your computer from a reputable electronics dealer means you're more likely to get a better warranty and better service. The computers they carry have succeeded because of the high-quality of their machines and their service.
  
• Another issue to consider as you prepare to buy a computer is vendors other than the most common brand names. The latter are often popular because of name recognition. Also, purchasing from them is simple, their prices are competitive, and they usually throw in some nice software to get your attention. That doesn’t necessarily mean that you are getting top of the line products or the latest technology through and through. Do your homework as you prepare to buy a computer to make sure that what sounds like a deal really is a good value.
  
• Almost all computers are essentially made from the same parts. Technical support sets one company apart from the others. Check to see if the company has toll-free numbers. If you buy an extended service plan, double-check to see what it covers. Sometimes the extended warranty only covers after the initial manufacturers warranty expires.
  
• Technology changes rapidly. In order to avoid having an outdated system within a short time, buy the newest technology. Also be sure to make sure the computer is able to be upgraded.
  
• Aside from the operating system, one of the most important pieces of software to look into as you prepare to buy a computer is a good antivirus program. You should purchase the latest version from a reputable company and update it immediately.
  
• You may also want to look for a good spyware remover, although you can find some excellent versions online that you can download free of charge. Lavasoft Ad Aware is a good one, and it is free for personal use.
  
• Keep in mind that the size of the software you plan to run will dictate how much memory your computer should have. Consider how you will use your computer, then ask about the software you'll need. A sales associate should be able to tell you how many megabytes of memory you'll need based on your planned computer use.
  
• Typically, you'll need a minimum of 64 megabytes of memory to adequately run most programs. Most computer systems come with preloaded software. Be sure to check the inventory of what's on the computer, so you'll know what you're getting.
  
• Decide in advance what features you would really like to have when you prepare to buy a computer. One example is looking for a system that offers Universal Serial Bus (USB) ports in front. Even if you don’t see the need as you prepare to buy a computer, you’ll likely find many uses for ports later. It’s much easier to access them from the front than to maneuver to connect something to the back.

The above tips should prove helpful as you prepare to buy a computer, but do as much research as possible to make sure you get a quality system that suits your needs.
