Should it be wobbling like this?

I can't feel any undue vibration through the chassis, but i've never watched a prop on the go before lol

NO it should not be like that

I wouldn't be happy with that.

I would stick a clock gauge on it and see what the run out actually is, probably a goodidea to clock both ends and the middle.

I would also clock the rims and faces of the flanges on the diff and engine to make sure one of these isn't damaged, if both of these are flat and true then I would contact the prop manufacturer tohave the prop checked for starightness.

Don't look good to me
but if it has the rubber cush drive that may explain it

No rubber cush it's a TRT prop between diff and reverse box.

Pezza mate, take it back to whoever made it for you, if you bought it like that then I'd send it to somewhere like dunning and fairbank in Leeds and ask them to balance it for you.

balancing wont fix a prop that is not true. looks like it needs to go back to me. before it takes a chunk out of your leg.
