If the chamber is metal, and you're using a 1/8" fitting somewhere, then just get a 9.8mm ring crimp connector and attach it. Or tap an M3 somewhere and use a 3.4mm of same.

distance between centres - 125mm

That's pretty tiny, it might be enough for your needs but keep it mind. To give you an idea, if you want to drill a 10mm hole, the cutting part of the bit is 100mm long, so the maximum part length is 25mm.

One of the reasons I went for the sherline is that it is 432mm centre to centre.

500 euro is not quite cheap for this thing...

I think it's too expensive for that lathe, and you may find the space you have between the centers is lacking.

and

They both have the option of a mill (witch I really really want).
The green one looks nicer but more expensive as well, what's the main difference beside look?

Don't forget to set some money aside for tooling, decent drill bits, cutting tools, taps and dies, files etc.

Emco is a great brand, when machining at school I allways make sure to pick the unimat :D

Quick question: what's the maximum diameter the unimat lathe jaw can grab?

Sorry my negligence, but what does what mean? I can put a rod with diameter up to 92mm in the jaw?

It means the maximum diameter the lathe can take is 92mm. The chuck itself is 65mm diameter, but the jaws are reversible so you can fit a part larger than the chuck body diameter, probably around 80mm.
