I've used PC690's for years, and really like them - other than the locking mechanism although I understand that some of the newer models use a different lock than the T-bolt on the older models. As I've gotten older, my hands have a problem tightening the T-bolt properly so I've been converting them to use an adjustable handle as shown - handle down is locked tightly and handle up is loose enough that the motor spins easily in the base. The router shown is actually the D-handle with one of Alan Warner's extended/offset bases which, to me anyway, gives a really stable operating unit. I probably like the D-handle model because it reminds me of my first router, a Sears with the trigger switch in the handle (stolen many years ago). I have another 690 motor, variable speed, mounted in my router table, one mounted in a fixed base like the one you show and one in a plunge base. I don't really need another router either, but would probably jump on that one for $99.
