As far as equipment goes exercise, hobbies, work or general play; you always want to make sure you have the right kind. This applies especially if you are serious or passionate about what you are doing. Picking the right equipment doesn't automatically mean you're going to pay a fortune. As long as you know what you need you can do the shopping yourself and not let those sales persons take advantage of you. A piece of equipment I try not to skimp on is sneakers. If you buy the right shoe for your activity and foot they will last you. Another piece I hope to start to not skimp on are bicycles. It is a new found hobby of mine that I absolutely love. I bought a used cheap bike off the streets and it has gotten me through some treks and many days back and to school. It has cost me more in maintenance than its worth so I hope to purchase a better quality that will last me years to come! A few sites that might help you with these purchases are:
