This comparison is incomplete, and does not reveal sufficient information upon which you should base a purchase decision.
You're not taking into consideration spindle quality, backlash, long term wear characteristics, parts availability, service life....and in some cases, the financial impact of your purchase dollars heading out of your country.
What about surface finish? Repeatability? Thermal expansion and a change in dimensions as the machine heats up....for subsequent parts? Stick slip of the ways, operator fatigue from cranking a cheap table,, ...and all the other subtleties of running a manual mill that only years of experience give you...
I was stuck with a Roundtower chinese knock-off for several years. It was a genuine POS. Could I get precision parts from it? Yes, I did. About 4 years ago I bought a brand new Bridgeport (now from Hardinge)...and don't regret a dime of the extra money spend over what a Chevalier or BridgeTower or Die Yung would have cost.
How accurate? It's not the machine, it's the machinist. You need to look at the oranges.
