The Lego stand ruled. I tried to make one, and it was nice, but I couldn't put much pressure on it or it popped apart. :ROFL:
Here's a perfect PSP dock, and it can be yours for $2 or less.
Here's a photo of the "dock" without the PSP:
I bought this in a local craft store. It cost me $1.50 plus tax. Here's a place you can buy them, in a number of styles and sizes (I used the 3").
I used one of those black and chrome large width paper clips (the kind where the black clamp spreads apart via the little silver triangular handlers - you can sort of see it to the right in my photo above) to keep my USB cable and charging cable in place when the PSP isn't connected (keeps the plugs close to the base, and makes things nice and tidy!). I'm thinking of adding a little bit of foam or rubber to the bottom and where the PSP touches the stand. The wire is rubberized, but I figure it could use a little more padding. This thing fits the PSP great and has an awesom BANG FOR BUCK!
PS. I also will be offering these pre-packaged with a 200% mark-up in finer game stores for those who think this is neat and don't know well enough to get them themselves. :lol
