methinks it depends a lot on what you are photgraphing. Indoors where you can control your camera and position, maybe with a step ladder, so you can keep film plane vertical will I'm sure work very well with an SWC. But I bet it doesn't work so well out in the street where you are limited with how far back you can get from a building, are at street level and need to point the camera up to get the top of building in shot. Its a question of the right tool for the job so there aer several cameras that might work and shift may not be necessary depending on your subject. But sometimes it will be so the OP just needs to be aware of this if he hasn't considered it.
A cheap mono rail 4x5 with short focal length lenses and a bag bellows should cover all needs. Infact most lightweight field cameras would probably do it.
A tecknikardan certainly would but is a bit too lightweight IMO. Not stiff enough although with short lenses its fine.
