Tell me this is a stupid idea and to just buy a Nord Stage. Will a Nord Electro 3 piano patch sound better if played with a weighted controller?

I'm trying to buy three instruments here, and they're pretty well segregated. A piano, a B3, and a wurlitzer electric piano.

I've tried all the high-end digital pianos available in the area shops - Yamaha S90, Roland RD, Korg SV-1. Last time I was recommended Kurzweil but the closest dealer is 2 hours away and I'm not crazy about buying without trying. I'm too picky - the Roland had an amazing keybed (and a so-so wurly & organ), the Yamaha had confusing menus, the Korg had weird action.

It's stupid, but I like the SV1 and the Electro because of the knobs. It feels more natural, more like an instrument. I can, for example, find the Leslie speed switch in the dark, or add effects quickly.

Should I just buy a cheap weighted controller (M-Audio Keystation 88 Pro) and plug it into a Nord Electro? It's $1000 cheaper than a Nord Stage, lacks a synth, but gives me a weighted lower manual and a waterfall upper manual.

My problem with the stage is the price, and the fact that I can't try it. After $3300 for the dp, I still need a good stand and monitors.

Crazy? Stupid? Have at me.
