Help choosing a used machine! Hardinge, Nakamura, Tongtai...

Hi all

Need some help choosing a machine from a shortlist of 3 please! This will be my first machine with a sub spindle and live tooling, I use Fusion 360 for post and I'm happy I can program for a sub spindle and live tooling. I really don't know what sets these machines apart from each other apart from brand and would welcome any and all help!!

I'm mostly turning small parts in lowish volumes but would like to experiment with possibly milling small parts from the bar stock in one of these? I don't know if live tooling can be turned 90 degrees to accomodate this. I'd really like to be able to use the one machine for almost everything if that's even possible.

They all have bar feed and chip conveyors, and a variety of live tooling and collets. They're all in the same price bracket.

Tongtai TA20LMB, 2012. Cleanest looking of the 3 machines, also the lowest hours. Single 12stn Snuter turret and tons of spare live tooling. Cheapest of the 3.

Nakamura TW10MM, 1998. Twin 12stn turret. Loads of collets though. 6 axis? Most expensive of the 3.

Hardinge Quest 8 51, 2005. Single 12stn turret (24 positions?), least live tooling of all of the machines but I believe this one also has a Y axis?

Full seller descriptions are below.

I really don't know what features I should be prioritising, they come with a 12 month warranty from the seller.

Thanks!
