Interesting Gav.The first site's prices do not include PDV or delivery, which may make a difference.
The B&D router has an interesting clamping system for the adjustable fence. It isn't the usual mazac casting. It also appears to have two fences, handy for morticing.
The Mannesmann looks like yet another MOF96 clone. Those things are far more useful than most buyers realise. All sorts of other makers' accessories fit them. I use an Einhell one with a Ryobi Fine adjustment fence, Perles fine height adjustor and Trend guide bushes, all of which work as if they were made for them. They just get marketed as cheap routers, which is a pity, as being very standardized, they have much more going for them. Four or five cheap routers set up for specific jobs can be very handy and cost no more than one dearer router.
