Wanted: Commuter bike

The Avanti 1990s model (that used foam as its suspension damping) that I have reliably used to get to and from Hornsby station is on its last legs (erm... wheels), now that its front fork now moves up and down freely and the wheel jolts when I apply the brakes.

I can probably fix it, but don't really have the time to do so.

Does anyone have an old mountain/road bike that they'd be willing to give away/sell at a low price to fulfill this need?

The requirements are simple:
- Good enough to reliably get me 6km several days per week but
- Not good enough looking that anyone would want to steal it or be a problem if it WAS stolen if it were left at the bike lockers.

Let me know if you have anything lying around. Maybe it was used at this year's BMORC Bash and you don't know what to do with it
