That's a good summary. To put it another way, this is really just a box that does programmed temperature cycling. This is a critical part of PCR, but there's nothing too terribly high-tech here. PCR is a relatively simple process. PCR is frustrating for the undergrad? Sometimes. Historically dependent on overpriced equipment? Absolutely. Dependent on small temperature variations? You bet. Complex overall? No.
