Recommendations for affordable X-Y digital readouts?

I'm seeking an *affordable* 2-axis DRO to use with linear scales for
my Taig Micro Mill, one with both absolute and incremental modes. I've
written Klaus Zietlow re his DRO-2 and Scott Schumate re his DRO-350,
but both are out of stock for the indefinite future. Have you any
other recommendations? Thanks in advance for any help you can give me.
