Having spent too long researching these over the past few days, I'd learnt that an independent 4 jaw was going to be the most useful, therefore I'll probably take the package & just flog the 3 jaw chuck on (most comments I've read suggest that you never go back to a 3 jaw after using an independent 4 jaw!).

I genuinely don't know what size tooling it uses yet (I'm hopefully going to see these at his premises tomorrow)

Here's my initial shoppinng list...

the lathe ith independent 4 jaw chuck.
tailstock chuck
A cutting set! (was just going to go HSS as I have a grinder and read that it's easy to maintain these youirself)

nice to haves...

lever tailstock
Quick change toolpost.
proper boring rod.
