We still have a 10 year old Partner 1 Centurion 5 with the original monitor. Our VM 24 has an LCD Monitor with a Centurion 6 that still looks like new. I'll take the Centurion 6 over the Centurion 5 any day. The 6 is much, much faster, especially doing 3D.
Sounds like the ebay item was bought by TZ250?
If all you're going to cut is aluminum, then I wouldn't be looking at a knee mills. Get something that is enclosed with flood coolant and high RPM. Our old Partner 1 is small and enclosed with 6,000 RPM and it's not fast enough. I know coolant is a pain, but can't imagine cutting without it. Been there, done that, never again. Carbide + Coolant on aluminum and you'll never (well almost never) have to buy cutters again.
