I used one of these (Bosch 1200W POF 1200 AE Router | Mitre 10) and modified it as per the wiki (Bosch POF 1200 z-axis conversion guide).
I did add an octopus strap on top to help the Z-axis retract.
I do have a spindle and plans to build a meticulous Z axis that fit it, but in the meantime, this works perfectly for me.
