The AL320 has the 3 axis display ( really only a two axis unit that lets you switch between 2 scales ) but i never bothered fitting the scale to the compound slide as it is not something i think i will use and not worth the hassle but you may like it and for what the extra cost is may well be worth ordering the the 3 axis unit .
I usually use the carriage to machine close to the length i need then use the dial on the compound slide to nibble away the last bit and if you are having trouble with the type of dials on the machine (metric v imperial etc ) just set up a dial indicator and use that to tell you how far you have moved the compound slide .
Fitting a 3 axis system to the AL50G would be problematic with glass scales as i don't think you can get small enough ones for the compound .
With this lathe i ended up fitting the carriage scale along the front under the apron as the motor makes fitting it behind the bed difficult and i had to make some custom mounts to hang the cross slide scale off the end of the cross slide
