What cnc lathe to go for?

Hi,

I seem to be going around in circles, im trying to decide on a new twin spindle multi axis lathe. I manufacturer rifle silencers, mostly aluminum work, some stainless.

The Machines on my list, they are all very similar in price.

Victor Vturn-A26 / 85YCV (YSCV)
Takisawa TS-4000YS
Takisawa ex910 (I have heard this machine has bugs in the control system?)
Hardinge GS 200 MSY with the big spindle option.

Any help would be much appreciated.

Thanks
Darren
