Dean machined some shutters to the correct the spacing (which was to long) to the Compur specification and found that greatly improved the performance of poorer performing Angulons. If the spacing's is too far apart coverage suffers.
The OP wants a budget WA lens, his camera has no movements except front rise so and good 90mm f6.8 Angulon fits that requirement and so would a similar WA Raptar..
Bob, I think you'd be rather surprised just how good these 90mm f6.8 Angulons can be, I use one with my cameras, Crown & Super Graphics, in Turkey/Greece hand-held and with a tripod and people can't tell the difference when images are compared to those made with my 90mm f6.8 Grandagon or 90mm f5.6 Super Angulon. Sure the latter two lenses have far more coverage than the Angulon but my 90mm Angulon covers 5x4 with no vignetting or corner softness and that's all that matter.
Randy, while your camera has a Focal plane shutter you'll probably get sharper images using a lens in a leaf shutter hand held. It's also quite easy to focus on the GG screen when working hand-held, then use the wire finder for final composition.
