I don't want to sound like sour grapes, but I have a lot of routers with plunge bases or that are plunge routers that are just about the size of this Colt router after the base is added. Yes, it is lighter, but I think the real advantage of the Colt was the one-handed operation and how it nestled in your palm. I was looking for a plunge base that would allow me to have a short plunge action using the Colt as it was originally designed--as a one-handed router. If you were allowed to have a plunge action with adjustable return force, you could do lettering and small, detailed work within a workpiece that other plunge routers are not designed for. This would require some innovative work to keep the plunge mechanism out of the way of your palm, but that would make the Colt a different plunge router than all the rest. Oh well, this is probably like a lot of my ideas--a product for one customer--me!
