Stalker1 is a nice techy-type font; I used it for the text of a barcode. It looks very machine-readable, if you know what I mean.
I LOVE Fallout; even Tactics, which was a commercial failure. FO:BoS is the only Fallout I cannot love. I'm also not holding out hope for FO3.
I can do some grunging-up if you like; scratches and gouges and faded text and such. If you're using adobe, is it a .psd file you're using? If I could retain the layers, it would make it MUCH easier to grunge up the text and the button surface separately.
