the real bull one looks a little better, larger motor, but not much info on it to be honnest... i.e. does it still use a 2 speed gearbox and the motor is a brushed DC motor,

Hi Gazz,

The Real Bull is the same design as the Sieg (both clones of some long-forgotten Russian machine, it is said). There are detail differences; the saddle is square on one and H shaped on the other, the RB has a nut on the end of the leadscrew to adjust its end float (the threaded stub which the nut goes on gives a good start towards fitting a handwheel on the leadscrew) and the RB has a sprinkling of oil ports to help with lubricating the leadscrew and saddle. The RB is available with a 4" spindle flange to take the larger chuck. The 2-speed gearbox is exactly the same. 

As an example of the general interchangeability of parts, a pal of mine has fitted a 4" RB spindle bought from Amadeal to his Seig C3: http://mikesworkshop.weebly.com/headstock-upgrade.html

Choices, choices....

I can see the bigger chuck is a deffinate advantage,

and the real bull has a more powerfull motor, but apeers to not have a cam lock tail stock, tho it's pretty easy to modify i guess... something to do on the lathe when i get it, along with making up metal wheels to replace the plastic ones on the tailstock and saddle.

I'm now leaning heavily towards the real bull (naff name, but i have a vinyl cutter, so can soon change it to something even naffer  :dremel:

Need to find a few more things to sell on ebay (anyone need any halstead finest gold boiler bits, got heat exchangers, valves, pump, fans etc :) then measure the smart and see if it'll fit in the boot, or i need to take the trailer, and a trip to laandahhhn is in order me thinks.

I see he does a quick change tool holder for 33 quid or so, is it any good? it dosent look like the ones i see for double that money, i.e. no big lever sticking out to operate the piston to lock the holders in place.

The tailstock should be easy to modify, Gazz. If you look at Arc Euro's pic of the C3, theirs seems to be basically the same casting, but with a lever and a cam arrangement to pull up a plate under the bedways, hence clamping the tailstock.

Dunno about the QCTP. I have a cheapo one of a different design, which isn't perfect but much better than no QCTP at all. You need to check the availability of extra toolholders; if my experience is anything to go by, you will need at least 10. I make my own, but this would be difficult without a milling machine. There are DIY QCTPs which can be made entirely on the lathe.
