thought I would get some quotes for rails, china want £638 plus shipping for 15m of linear rail and 6 carriages odiously its not going to be real hiwin were as cnc4u is £989 for the same but real hiwin. This is just to do a single rail each side for two axis which would obviously be nearly double to do 4 axis and have the two rails each side.

ether way I think I may be back to looking for possible cheaper solutions, I was wondering about round rails if I did the two rails each side but not sure there would be that much saving in cost.
