Computer keyboards like anything else can range in price, the more expensive are usually better depending on what you need, ie a more expensive Keyboard might have more features such as buttons to click on the keyboard, one click and your on the internet, one click and your checking your emails, some even allow you to program the buttons yourself.
Another reason why a Keyboard may cost more depends on if it is wireless or not, wireless Keyboards cost more but reduce the need for wires and you have more freedom to position your keyboard without having to worry about pulling it too far and causing the wire to come out the back of the computer.
Many people just focus on spending their cash on the hardware inside the computer and then just buy the cheapest Keyboard they can find, this is OK if you do not use your computer much but if you are on it for long periods you may wish to purchase a higher quality Keyboard, and if you run lots of programs you may want a Keyboard with one click button functions, this saves and lots of time and makes it more efficient.
Sometimes it is not possible to lean back in your chair with your wired keyboard connected, wireless keyboard can make this happen, allowing you to relax while you check your emails or check the web, whatever it is you may want to do, wireless brings new possibilities to your way.
