I'm not sure there is any real dividing line. Some professional retrofits
don't require great accuracy, large workspace or high rapid feeds.

Some hobby retros are built with very high accuracy, on Series II
Bridgeport iron, with high speed servo drives, because the owner
has the budget and time to do it right.

If you make one-off jobs, the rapid feed speed will make no
difference in most jobs, as the setup time will completely
swamp it. If you make 10,000 piece runs of a part, a poor rapid feed
rate could make it take 10 x longer.

If you are going to be making hydraulic control valves for the F-29,
you probably need a very accurate machine. If you are going to be
engraving nametags, you probably don't need such precision.
So, it depends most on what you plan to do with the machine,
how many hours/month you will be using it, etc.
