As much as I'm not happy with any solution for LCD screens, the time has come for me to rid my home of old CRT TVs.

So up for sale is a pair of Ray Gun style Act Labs S-video USB light guns.
This model has the guns permanently wired to the interface boxes. They show up in windows as usb mice.
Personally, I find this model the most comfortable to hold and use.
THESE ONLY WORK ON CRT (tube TV) SCREENS USING AN S-VIDEO VIDEO CONNECTION.
There are a few very high end CRT TV's with built in line doublers or filters that prevent them from working, but they are rare.
They work just like you remember the light guns of old working.
There is a white flash of the screen and your shot is accurate to within 3 pixels no matter what height or angle you are shooting from.
They are in excellent condition and work perfectly. They are dead on accurate in windows as well as emulators.
$100 shipped within continental U.S.
Paypal only (or cash in person)

I also have a pair of the newer small silver pistols. These are also S-video models.
These guns however are detachable from the interface box, so could be swapped with the arcade style guns if you happen to come across some.
THESE REGISTER AN INCH OR TWO HIGH IN WINDOWS (can be corrected for in calibration screen of emulated games) AND I ONLY GUARANTEE THAT ONE WORKS.
I took one apart and tried bending the sensor to correct the aim in windows. It seemed to make no difference.
I remember it stopped working at one point, but don't remember if it started working again or not. I don't have a computer near the CRT TVs in the basement (they are going to recycling on Saturday) and don't want to bother with testing it. I'll tell you upfront that I find this design uncomfortable in the hand.
$30 shipped for the pair in the continental U.S.
Paypal only (or cash in person)

Guess if anyone local wants the CRT TVs they'll be available until Saturday.
Both are RCA. One is a 29" IIRC and has S-vid & composite inputs.
The other is a 36" IIRC and has S-vid, Component, & a dedicated original xbox input for which I have a component cable adapter for.
