Since Hail is no longer doing this, I'll do it.
pretty much the same as the services he did, I replace the old blurry screen with a better looking, more efficient one. You send me your nomad and I'll install the new screen. price is $50 via paypal. If paypal isn't an option for you, we can work something else out.
Also doing battery mods now. What I do is take one of the old clip on battery packs for the nomad (the old rechargable ones or the AAA ones, I do both) and install a new lithium ion rechargable battery rated at 2500 mah. If you provide the battery pack, it's $50. Otherwise, $55.
Also, I provide s-video mods for the nomad. stock, the nomad only had rgb (useless in the states) or composite out, but never s-video. This mod allows you to hook up for sega nomad up to your tv via a standard s-video cable (able not included). This service costs $20.
UPDATE!! Now for $25 I will region mod your nomad to play both PAL and JAP games. This is very useful for those in Europe since it was never released there.
If you wish to have all four mods done, I charge $120. If you want just the screen and battery mod done together it's $85. If you want either the screen or battery mod with the s-video mod, it costs $65.
Here's a sample of the s-video mod done on my own nomad.http://www.youtube.com/watch?v=Yes2_d1gUkY
And here's a video of the other mods I providehttp://www.youtube.com/watch?v=Bix64MUB ... tube_gdata
