The Q-pid is a crucial tool to Sam's journey across America, but you don't have to be trekking across the country to find the Q-pid a worthy addition to your collection.
The official Q-pid replica on the Kojima Productions website costs a whopping $325.00. It's amazingly high quality, but definitely on the steeper end of the price scale.
However, there are some unofficial replicas to be found. Though only two of a wide selection of options, this Q-pid necklace costs a much more comfortable $53.84 and another and even more affordable option costs only $20.09.
The option for you will depend on your holiday budget, of course.
