I don't own a mill/drill but I can tell you my experiences of buying a Warco pillar drill. The machine was very well made, well priced, and when I contacted customer services to ask about what initially appeared to be chuck runout, they called me straight back to offer advice and support. In the end it was the drill bits (which I sourced elsewhere) which were the problem not the drill. I've been delighted with the drill so if I was in the market for a mill or mill/drill then I'd certainly consider a Warco.

They display at various trade shows around the country so you might be able to see the machines in person. They bring a range of mills, drills, and lathes along so even if they don't have the actual machine you are interested in there should be something in that range to give you a feel for how they are made.
