The greatest thing about home gym equipment is the freedom.  You can work out whenever you want without a problem.  With a regular gym, you have to go when it is open, and you have to deal with all the other people who are there.  You can work out alone and on your own time when you own home gym equipment.  In any other case, there are factors limiting your self in some way, and with anything in life, we want to remove those limitations.

Unfortunately, many people buy gym equipment and then skimp on using it.  If you want to see results, you have to have a consistent workout regiment, and missing or skipping days can set you back a lot.  Sometimes having the equipment next to you can foster laziness, and when this happens, the only thing that can defeat it is powerful will and the knowledge that you need to keep pushing on. 

Depending on your specific body type and goals, you may need specialized gym equipment.  For those who are only trying to work out a small part of their body, then you will not need as expensive or as many equipments as someone else.  Those who want to get full body workouts could either buy multiple pieces of equipment, or get a single all-in-one unit that can transform in to everything necessary to exercise the body.

You do not want to get something you do not need.  The primary reason for this is the cost, as you would be wasting money.  Also, if you try to go past your limits, you can actually do damage to yourself instead of helping, and that is not good at all.  By honestly assessing your ablilties, you will end up with exactly what you need, and nothing more. 

There is a wide range of prices when it comes to gym equipment.  The small things are the cheapest, such as dumbbells and other popular, undersized tools.  Once you start working your way up to traditional gym equipment, the prices may leave the less-than-$100 section and get up in to the multiple hundreds, or even thousands. 

The capabilities you want in your equipment has a huge effect on what the price will be.  The bigger and better gym equipment is, the more it will cost, which is why you need to be careful in making your final decision.
