SGpro vs. Brevis... GO! (User opinions wanted)

Hi all.

I have toyed with building my own adapter for a LONG time now, and I realize how easy it is to get 90% there. It's that last 10% that Wayne and Dennis have achieved that makes ALL the difference.

I have narrowed it down to these two 35mm DOF adapters to add to my arsenal.

SGpro creates some AMAZING imagery from the footage I have seen posted, some of the best I have seen. But its boxy shape and DIY appearance, shims and setup time, etc. scared me away.

Brevis: Professional appearance, compact, light, fast set-up time. Image quality is NICE but murky bokeh and a more subtle DOF effect has kept me from buying.

So, my questions are directed to users/owners of either of these units.

1. Do any of you feel goofy using the SGpro due to its appearance only? Is it loud?
2. Does the new diffuser (CineFuse 3) for the Brevis address most of the image quality concerns (CF1 may not diffuse enough in certain situations)
3. Can the CineFuse3 be used in indoor situations, or are we back to using 2K fresnels?
4. The SGpro is SHARP. Are there additional optics within the Brevis that soften things up a bit? Can the Brevis be adjusted to be as sharp as the SGpro?
5. Are the achromats in both units comparable, or is one noticeably better than the other?
6. I have a DVX-100 Classic™. These cams have worse Minimum Focal Distance than newer DVX or HVX units. Will I need more than a +10 achromat to achieve proper focus?
7. Can the Brevis be purchased with the CF3 pre-installed, or is it only an optional additional purchase? (Perhaps Dennis can chime in on this one.)
8. Which adapter exhibits less vignetting with wide-angle lenses? For instance, I have a Soligor 17mm F3.5 - a nice lens, but will it work acceptably on either adapter? I am invested in Minolta MD lenses - anybody else have these and how do you like them?

I know there's a lot of stuff going around about these and other adapters, shootouts etc. I feel really fortunate to have the ability to purchase such nicely designed equipment, and you guys have both done an outstanding job. The amount of thought and problem-solving that went into both units is impressive.

Thanks in advance for your replies.

yeah, the brevis is bomb. I can't say I've ever used an SGPro, but I like my brevis. I have pretty bad vignetting issues with my zoom lens (28-135 f3.5-5.6) but it's certainly much worse when zoomed in to 135. th infinity focus at 28mm is a little lacking, and the micro colimnition wont go back far enough to accomidate how close it needs to by to the GG to acheive crispy sharpness at infinity, but I'm convinced I'm doing something wrong, so I've been brain storming, and I think I'll figure it out eventually...

anyway, my lenses arnt great, and I'm using the CF1L on a DVX100b.

I like it alot, but I just need to get a feel for how to deal with focusing, and most definetly vignetting issues... If you got the money for a CF3, I hear the nicer screens are ideal for eliminating the vig and I'm sure the focus is pretty killer.
 
The SGpro box shape dosn't bother me, id rather it was boxy and had a proper rod mount, rather than tubular and have an ugly wobbly bolt on stalk thing like the letus or brevis.

The SGpro is absolutly silent, no noise what-so-ever.
