1. Don't forget the software. Think about software from the very first - it represents what you want to do with the computer. Also, any machine you buy should come with the current version of Windows installed on the hard drive. You should also get it on CD-ROM. Be sure you know what other software comes with the computer, and what you'll need to buy. Note that MS Office XP is different from MS Office 2000 and different from Corel Office Suite.

2. Don't skimp on memory. The more memory a system has the better its overall performance. Most current new systems should come with at least 512MB and you may need more. You can also add memory later, and each computer has a maximum allowable memory.

3. Buy more disk space than you think you need. About 40 GB hard drive is the minimum you should consider on a new computer in today's environment. (40gb to 250gb is preferable).

4. Let your fingers do the walking. Check the computer magazines, newspaper ads, and shops on the web. Check comparison shopping sites.

5. Look for 30-day price protection. A reputable vendor will refund the difference if you buy and the price goes down within 14-30 days. You should also make sure there's an unconditional money-back guarantee, such as within 2 weeks to a month.

6. Use a credit card. You can double the warranty of any system by using a credit card with a "buyer's protection" policy.

7. Don't forget the extras You may want better quality speakers, or microphone, or graphics. Also, check if there's a modem. You'll need to buy an extension power-strip to plug the equipment in, and it should have surge protection.

8. Don't be frustrated when prices drop. Invariably, the system will cost less tomorrow, and new machines with better features will emerge.

Instructor's Note: Many stores allow you to return the computer within a period of time, such as two weeks. Find out what the policy is related to returns.
