Confusing...
Aren't all DC motors reversible? Why is this gear head motor YG-2732 getting praise for being reversible while this normal 6V DC motor does not get the reversble praise?
I never heard of a store bought DC motor that can only go in one direction.
Which one should I get? Value or Performance?
I'm building a holonomic drive robot platform and jaycar is the only place I can find to find the proper motors.
If there is another place, tell me.
Or should I just use hobby motors?
Can you help me decide?

I don't know if you know
I don't know if you know this, but the first one you listed has a gearhead, the second does not.
You're probably going to want to buy a motor with a gearehead, else you want no torque and unmanageable speed.
Also, take a look at this motor: http://letsmakerobots.com/node/4937
I bought 4 of them, they have a built in encoder as well, they're great!
