Making informed decisions about the purchase of equipment of any sort are very important to Sheldon Wright. He looks at it not only as an investment but also something that's good quality that he wants to enjoy for a long time with minimal technical problems if any at all. This is why he is really into making product comparisons before that ultimate buying decision. The best thing you can do for yourself before buying any product is to be informed. He has bought products that he has regretted which could have been avoided had he spent time researching beforehand. He knows people are busy today so this is why he has put the time into gathering information about various treadmill brands that would make it convenient for others looking to buy one. As mentioned before in his other books, it would've been much easier to have an available guide to help him out. He no longer needs to buy a new treadmill; but if you do, his guide book is a great resource.
