Quite understand Michael.
It may also be worth pointing out to Alex who may not be familiar with the BCA type machines is that although they do indeed have a very nice 8" rotary table it is fixed in the horizontal position and in the long term if this is to be a sole milling machine the lack of ability to have a vertical or any other angle for that matter rotary table may be a factor in choosing a suitable machine.
The relatively low head room on the BCA does not lend itself well to use with a small vertical rotary table so thought should be given to the possibility of using a milling spindle and dividing in that lathe and also how any future work can be accommodated.
Not trying to put anyone off a BCA or cost Phil's friend a sale but not something to rush into just a something that may suit is available
