Damn...first one to vote.....hehe.
I would scrap the ones with all the consoles and the ones with no consoles to start with. The crossfade is a nice touch--definately keep that in there. I'm a bit torn on the arrangement of the XBox and PS2 though. I think that's all you really need in there, since that is at the heart of what the mods will be on. I like the way you snuck the vertical PS2 behind the "P", but it doesn't really seem to catch the eye enough--when you look at it, all you really notice is the console shown at the other end of the logo.
Personally, I have a problem with the XB in general--it's a Micro$oft product, so I am naturally inclined to avoid it. If I had to choose one, I would go with Pxlogo4--it's a nice logo for the PS2 side of it. To include both the PS2 and XB, I would likely go with Pxlogo5--but I would like to try to make that vertical PS2 stand out a bit more. Maybe if it could be nudged a bit more to the left so you saw more of the side panel and the blue "PS2" label on it. This would require maybe a slight reduction in the forward layered "PSX-MODS" text to keep the banner size the same, or maybe a slight extension of the horizontal lenght of the banner to give the extra room for it to peek out.
Overall, they're all good. Impressive work for a "tinkerer" (hehe). It was hard just narrowing it to a top5, much less 1 or 2!
If it ain't broke don't try to fix it! But, hell if you can tweak that bastard just a little bit more....hehehe.
