I have a Sheline mill, non CNC but with DRO., Lovely little machine with plenty of punch. Only one issue and that is consumable parts and spares/upgrades. The 'T' slots are smaller than most machines found in the UK. You either need to make a plate to put on the table that you clamp pieces to, or order Sherline bits from the only real UK importer (MillHill supplies of Basildon) or import from the US.
Similarly the spindle is MT1 and as such limited ranges of fittings in the UK.
But plenty of parts made by Sheline of excellent quality
