If you choose the AXBB-E hardware and matching UCCNC software then buy the software license and hardware as a package. The license for the software is tied to the specific controller so you can load it on as many PCs as you like but it will only ever run the one controller. I bought mine direct from the CNC Drive website and was very happy with the service and delivry to Australia, but if you can get it cheaper elsewhere then go ahead. No doubt others will chip in with the best UK suppliers.
