There's a Denford Starmill on eBay right now. Looks like it needs a cleanup and probably new electronics but could be an excellent little machine.

Apologies, wrong link.

It looks like it is the same mechanical package as the Novamill, which I have and it's excellent.

To make any sensible suggestions we need far more information. For starters:

What maximum size of workpiece do you want to cut?

What sort of machining – 2.5D, 3D or full 4-axis?

How much space is available?

Budget?

What sort of steel, ordinary mild steel, or tool steels and stainless steel?

I have a Tormach 1100 which will happily cut steel, like these brackets in hot rolled steel:

By hobby standards the Tormach is a fairly large machine at 450kg, and is the same horsepower as my Bridgeport. That not withstanding I find the Tormach works better running small cutters at high spindle speeds rather than running large cutters at slower speeds. A high maximum spindle speed is important, 5100rpm on the Tormach. Even that is a bit slow for really small cutters. I have added a high speed spindle for use with small cutters, like this 1mm ballnose cutter, running at 24000rpm:

By the time you have allowed a small say 6mm tool to clear the work and for lead ins and outs that 5" Y movement will be in the region of 140mm which rules out the likes of the little Denford that John showed.

Its about the limit of my KX3 so you would be looking for a machine of that sort of size as a ready to go CNC mill or something in the same size range if you wanted to convert. The Tormachs have a better X to Y ratio so the 770 would do.

You are going to need a good 4-5ft of width and 3-3'6 of depth plus room for the screen & keyboard,
