Michael: As Tony said, a Kowa is a good choice. Don't forget about the bracket. Classic Home Cinema manufacture a very low-end one that can be attached to your projector (providing there's a thread) and that does the job nicely. Or you can look for a free standing one. Watch Derann's used list as they pop-up regularly there.
Jan: You need to focus your primer first, then "fine-focus" with your scope lens. They work fine with zoom lenses (I also have a 1.1). I don't know if there's such a thing as a "zoom-scope-lens" as scope lenses are more optical extensions than actual lenses (hence the need for a primer). A scope focusing film is handy (Derann sell one), it's basically 50ft of test card that will allow you to focus your primer, install your scope lens (that's where a swing away bracket comes handy) and then fine focus your scope lens. A good print with a recent cartoon (even not is scope) will do the job as well. And I mean real cartoon, not CG. Once your scope lens is in place, you can adjust focus directly on your primer during screening (the primer is more subect to shift when the projector is running). And yes, there's a slight loss of light output, so don't try to project The Fog with a regular 12V/100W bulb. Hope this helps.
