Adobe,
I can't say enough about how important precision homing switches are. Many times I feel that it falls on deaf ears with the benchtop hobby guys. An investment in a few high precision switches on ebay will save the day every time a servo faults or program crashes. Home then run from line #.
The DRO is a great alternative to them but having both is the best possible situation.. So far as using a dro with rotary encoders, it would have to be a software/hardware programmable virtual dro. I don't think a dedicated box dro has the ability to be programmed for # steps per inch so if you dont build your machine to it's exact scale formulas, it won't work properly.
