Personaly, i think those are Cr*p. A lot or most had Yasnac controls, good luck getting service. Hitachi went bankrupt, Mori Seiki was asked to take over from the bank. Parts can be tough to get. Used to get calls on those for very strange problems. 7K is way on the high side IMO, i would try to find something like an Okuma LB15 , or even a little newer like an Okuma Cadet, either one of those I see regularly for 5-8K.
