Most of your comments are over my head but I want to make my own stuff so I will figure it out. Still seems like that size is too much for our hobby.
Looks like a nice machine, like the power crossfeed and reverse feed. They are 25 miles from my home and never heard of them? The slim live center would be a good option if you with them.
Here's a photo from yesterday, was center drilling a piece stock to hold the rod end screws while the heads were faced. Took 12" of the way just to drill, needed to push the tailstock out of the to tap, this is why a larger machine is better. I would get the 30" bed if possible
