Biotechniques.com : Cheap PCR: new low cost machines challenge traditional designs

Although PCR is a fundamental tool for many biologists, thermal cyclers—essential to driving PCR reactions—have not yet become easily affordable or widely accessible. An instrument’s expense, which is between $4000 and $10,000, has essentially confined its usage to university laboratories, and excluded entities like public schools or field-based health initiatives, which could benefit from easy access to DNA amplification technologies.
