Well, if you're looking for an excuse to get a 1400 or 1010 then by all means, proceed. "Dang it! The router is on the lift! I gotta get me another router."
If the 2000 is sitting there collecting dust, a total waste, well then, you've got a point.
Otherwise.....
You are only saving the cost of the motor. You still have the top, the fence, the lift, the table, the casters, the on/of switch with the big red safety flap, and any bits that are for table use exclusively. A single nice set for cabinet doors will cost as much as a motor. Plus whatever time it takes to put it all together. And making the the 2000 work will take more time.
$70 extra for above the table bit changes? And I just don't know if I'd trust that little gizmo with my hands. An insert for 1/4" bits? Hum. It's possible for spiral bits to climb and punch right through the piece. And sometimes I push a little too hard on the workpiece. That extension sure puts the business end of the bit a long way from the bearings.
Power. Nothing wrong with the 2000 but I'd go for as much power as I could get. Check out this cool
Milwaukee/JessEm rig on Amazon. 3 1/2 horses and speed adjustment outside the router body. Sweet.
Dust collection. To get good dust collection you need suction above and below the table. For me that means an enclosed box with a 4" dust port and a port on the fence with a hose that goes down to the box. For me a small vac like a CT is out or the question.
My router table is a workhorse. I've had the motor running continuously for 10 to 15 min at a time running profiles on moldings and doors and drawer faces, cope and stick bits and slots for door panels and drawer bottoms. I wouldn't want to subject a precision tool like the OF2000 to that. One time I forgot to turn on the dust collector and the whole unit, router motor, lift, plate, were all too hot to touch when I was done.
There are so many interesting lifts to choose from. One very intriguing model is the Quick Lift, also from Woodpecker. I've been looking at that one myself. The only reason you're looking at the Unilift is because it may support your plunge router. You'd never give it a second glance otherwise.
And to top it off, it's a bit insulting that Woodpecker didn't include a bolt pattern for Festool.
