Hi Martin,
I am in a similar position as you and have written on at least two occasions to Warco in regards to their service as advertised in their catalogue, and after two months am still waiting for a reply.
Next month I shall visit their premises for a final check on the VMC turret mill with R8 spindle and obtain pricing to include DRO's and power feed to the x axis, and this all to include delivery and installation in the workshop.
As soon as I get a reply I shall let you know, and hopefully vice versa.
I am only aware of the installation service from Warco and I am not sure if Chester or Toolco offer such a service.
Best regards,
Mike
