Goat milking machine?

Earlier this year a farm couple was killed when their van was hit by a drunk driver that ran a stop sigh. (So sad!)

Anyway, their farm machinery, etc. is being auctioned off later this month. In the ad there is a "goat milking machine". Anyone know anything about these? What they're worth? What to look for? Etc. etc?

If this gomer bull enterprise of ours works out and our nannies stay alive, it may be worth getting a milker. (And my hands wouldn't get so sore.)
