Well, that settles it, then. When I get my Holga (birthday coming up soon ), I'll get one from Randy and have him do the basic modifications.
I think I'll also try some of Freestyle's house brand of color film in the Holga. Always used black and white in the old Holga's, but some "off color" might be fun (gels, "incorrect" light source, etc.), and the Arista film is cheap enough to experiment with for that purpose.
