Or i do mod a Camera by myself into a Pyra.I would suggest then that you get a half-decent pocket camera. since you'll have to be wearing a big coat or taking a bag to carry your Pyra around, I'd propose you could also carry a camera quite easily. You can get quite good pocketable cameras from a generation or two ago for around 200 of the major world currencies, which should be affordable if you've got a pyra preorder.
Remember my Pandora Wlan Mod?
