Newbie G0704 prefered over X3?

I've seen a couple post stating that the G0704 is preferred over the Sieg X3 based machines. Can someone help me understand why that is? I'm coming from an Enco RF30 clone. On paper it would seem that the X3 machines would be better because they weigh over 100lbs more than the 0704.

I want to build a mid sized machine that I can get a comercially available CNC mount/ballscrew kit for. These two machines fit that bill.

I'd just keep my machine, but I don't have the time or engery to make my own conversion. Another option I have looked into is buying a Dyna 2400 CNC mill. I found one that I could pick up for around $2500, but it is a pretty small and slow machine compared to a conversion.

Thanks,


Chris
