derivative, it is actually a programmed PIC microcontroller (or maybe AVR).
The frequency accuracy, power pins, and general frequency range are what I'd
expect...
So to answer your question, I could make one myself in a couple of hours or
less. A single-frequency version, much quicker than that.
Still, it's a handy thing to have available for people who don't want to
program a microcontroller for every simple project.

When I say I could make one, that doesn't mean you shouldn't buy theirs. If
I knew how to use a metal lathe (which I don't), I'd be able to make my own
nuts and bolts. But that doesn't mean I'd never buy them at the hardware
store!
I rather like the Hightechips approach to packaging preprogrammed
microcontrollers as solutions to analog electronics problems.

Their secret being writing a bit of code and burning it into 35 cent

Bit dishonest and pointless of them to pretend they are not doing this.
