Hardware TOTP tokens

[Dag-Erling Smørgrav]

I'm looking for *rekeyable* TOTP (RFC 6238) tokens - preferably, but not
necessarily OATH-certified.  Does anyone know where I can find something
like that?

Alternatively, does anyone know of a reasonably-priced device that can
be used to implement this?  The requirements are very modest - a cheap
microcontroller with a few kB of EEPROM and few kB of RAM, a reasonably
precise real-time clock, and a six-digit seven-segment display, all in a
package the size of a pack of gum.

Note that we're not talking about large volumes - I need a few hundred,
at most.
