Hi Gary

There is also the 565, which is also pretty cheap along with limited capabilities in today's terms.

Personally, I would invest in a 568.2/568.2mm as they were the final versions made and therefore the youngest.

The 500 series processors have limited inputs, I imagine because of their size; in order to facilitate bigger systems/additional sources, the 562/562v was available.

I currently have a 565 and a 561 unused, if they are of any interest.

Best of luck.

Regards

Jon
