The Worksharp isn't that big - well worth the space in the cabinet, if you ask me. 

I came from the world of Japanese cooking knives and water stones, and took the same approach to chisels, for a time. Then I decided that I didn't want sharpening to be a hobby, in and of itself, but rather something that simply supports woodworking. Got the WS3000 and have been happy to give sharpening little and infrequent consideration since.
