Since the MultiRouter was brought up as an alternative to
the Leigh, PC and the AKEDA, you might consider another
alternative - which eliminates the centering of the bit and
the roundness of the guide collar - the JoinTech Cabinet
Maker precision positionable router fence - with dovetail
templates. In addition to through and half blind dovetails,
box/finger joints - it does all the other things a good router
fence on a decent router table can do. And it does permit
variable spacing of dovetails. And unlike its competitor
it has a built in centering feature - eyeballing being one
of the problems with the competitor.

No fingers that can move, no flexing of the finger support
bars, etc.
