In model RR equipment, to a large extent you get what you pay for. A typical high quality plastic HO scale diesel model today will retail for $100 or more. Certain close out discounts may price a quality loco as low as $30 from time to time. I cannot tell from the linked site who the manufacturer is. Quality brands, many manufactured in China, include Kato, Atlas, Proto2000 (Life Like), Athearn (especially Genesis line), Broadway Limited, Stewart, InterMountain, and Bachman Spectrum. I'm sure I missed others.
Although this model appears to be manufactured in China, this is no guarantee of quality. If it is an off-brand, then cheap may really be costly, in that the loco will not run well (many reasons) and may have a poor paint job and oversized or missing details.
