Gearbox bearings wiggle a bit

The bearing on my 4 speed output shaft, clutch end seems ok. They dont feel gritty or make a sound when spun but I can detect a slight wiggle. Replace?
Also the Fourth Gear has a slight wiggle as well. Maybe 1/2 mm. Is this ok?

Not a very good video but you can see it a bit.

Background.
Gearbox had a fair bit of metal on the drain plug and the gear box whines (like when you use reverse gear in your car). Gearbox developed oil leak front and back when I unwisely used synthetic oil to quieten it down (which it did incidently). So I took a deep breath and decided to open it up.
On inspection the gears are pitted but all the bearings seem ok except the bearing at the back of the input shaft. It looks older than the others and makes a bit of a sound when spun.



Thanks

With pitted gears I'd be looking for another good used box.

Prices vary, usually between $250 and $450 on ebay. Some very good deals can come down the pike, but buyer beware.
