Nick, I've had one of these from new in around 1987 and is the target of my CNC conversion thread on the forum.
http://madmodder.net/index.php/topic,7345.0.htmlIt is essentially a 6x26 but without the fine quill feed wheel - a feature that I've not found a problem.
Naturally it will have similar design compromises but in order to earn the Myford label, they were imported into the UK and stripped down by myford and the slideways scraped and generally given a check over. Mine also had a British/eu motor fitted as at the time, Chinese ones had a bad reputation. I had one on a drill press that was badly balanced and soon became a doorstop.
In any case I now run the VMC with a 3 phase motor and inverter.
The machine in the photo looks very clean and has possibly had little use as the paint usually gets stained by oil/coolant etc on hard worked machines.
Provided the feedscrews and nuts are not badly worn, I'd say it is worth getting at 2/3rds new price.
Note that spares will be no more available for it that warco/chester machines.
If you are looking for a target for CNC conversion there won't be much that Rob supplemented by my project experience won't know about the task. Feedscrew condition will then be irrelevant.
