The advertised 280V-F looks a good buy; I have the 250V-F & the work I have done, albeit small, has been competently handled by the machine. Although I try not to put too much doc on, I have taken cuts of 1mm using tangential tool without any bother so the 280 should handle most things easily. As for after sales, Warco have been most accommodating with the issues I had with my lathe, & WM 16 Mill, & some tooling that I bought so they are fine in that respect, cannot comment on Chester / Amadeal as have had no dealings with either.
