What are these walmart clones I am hearing about? I checked my walmart and could not find them but then again I didn't know what I was looking for. Who makes them and how good are they? I curently have 1. microsizer 2. zip zaps and 1. nikko ir racer and I parted out a hotwheels kit racing car for the moter, gears and battery, not bad for $10. I am looking to expand my collection.
