camera adapter issue

I have a canon S400 and a few months ago I got the maxview pro 40 adapter for it. The problem w/ my camera is that it has no threads so it needs an adaptor mount which then you could attach the maxview pro eyepiece specifically. This is really tough because I can't use higher power eyepieces for planetary viewing that specifically attach to that adaptor (you can see what I mean by looking at the maxview pro adaptor for my camera in scopetronix's site). I was wondering if anyone out there had a not so expensive but worthwile solution to this issue. Thanks a lot,

Mauricio.

Barlow? Powermate? Or possibly one of those devices that clamps around the EP and holds the camera in position over a regular EP?

That's about it I think.
