What 'decent' Milling machine?

[Chaz]

Having previously designed and built a CNC machine, I learnt a lot about what works and what doesn't. I dont want to waste time trying to get a machine to work as needed, I managed to get semi decent results, the kit was decent, but not sure my design did it justice.

So looking at this again however keen to buy something that is ready built and works.

I have 2 main requirements, a bit different, hoping that there is a machine that can do both.

The first is cutting of 2 gears, in brass or plastic. I have previously milled these from the 'top down' but had issues getting 100% centre when the one gear was flipped over. I believe now the better way to do that is to make 2 parts and join them together. A lathe is probably better to make the 'blank' and then use something to cut the gear slot. I dont know if these gears are custom or not. I have measured them and cannot find a module number they comply too. Some pics should be attached.

The second need is bike parts using Aluminium. I need something that can automate the production of a number of pieces as far as possible. Parts will be things like rear sets, levers etc.

Ideally it should have a auto tool changer or one where I can simply remove the tool and apply the new tool without having to reset the Z all the time.

Ive looked at a number of machines from companies like Axminster, Amadeal etc.

No fixed budget, cheaper is better but willing to look at machines that are anything up to £10K. Doesnt need to be new, 2nd hand also welcome. My preference is something that connects via USB like the PlanetCNC card or similar.

Size wise, not massive, but I dont want to buy too small and be stuck. A milling area of 300mm x 300mm sounds reasonable.

Any suggestions?
