Hi Jeremy,
I wanted to inform you that our website has been updated in regards to the specifications for our TV USB Light Gun.  The good news is that it now supports S-Video input only and either S-Video or Composite video output to your TV.  This is in response to many requests we have been getting about the improved picture quality of a pure S-Video signal compared to Composite.  A second improvement we are going to implement is an increased light gun cable length.  We will extend this cable to 10 feet.   For an increased USB cable length, we suggest purchasing a USB extension cable but we may extend this cable lenght as well.  Also, for the two player light gun issue, we are looking into this matter and working alongside game developers.  Future light-gun-supported-games may have a two player option as a result.    
I'm also glad to inform you that, with all these improvements, we plan to keep the price point for our TV USB Light Gun at approximately USD $39.99.  Please feel free to inform anyone and everyone who is interested in our TV USB Light Gun of these improvements.
Regards,

  Hi,
  I recently saw your announcement about preorders for a TV 
based lightgun,  and while it would normally be a product I 
would buy instantly, there are  some limitations that keep 
me from ordering it at the moment:
  1)
  The chief being SVideo input to the TV.  Basically, I (and many 
in the mame cabinet development community) have spent a lot 
of cycles in design time creating our systems to support SVideo 
from the card to the TV, for reasons of  improved video quality.
  The idea that to use this product we would then have to 
DOWNGRADE to Composite is unacceptable to many of us.
  I personally (and likely many others) would  be willing to 
pay more for a product that meets my specifications rather than 
none at all for one that  doesn't.
  2)
  The issue of dual gun support is also a stopping factor. As I 
understand it,  this is because the ACT-LABS interface uses the 
USB HID mouse support and windows can only handle a single 
pointing device. I would vote, instead,  for something more 
flexible like the HID Joystick interface.  MAME and  others 
could easily add support for multiple joysticks whereas Windows 
is locked to one mouse (though I'm running in linux and do not 
have that restriction)
I would be more inclined to create my own positional gun setup 
where I could  connect two guns rather than purchase a 
product that limited me to a single  gun.
  In this case I would also be willing to pay more for  something 
that meets my needs as opposed to nothing at all for something 
that doesn't
  3)
  The size and shape of the gun has caused some consternation among
  individuals in the community. (gun too short, USB cabling too short,
  Reload button with odd placement for left handed people, or people
  who would want to play with BOTH guns simultaneously)
  I'd be overjoyed if these issues were addressed, but it would not
  hinder me from buying a gun if issues 1 and 2 were addressed.
  Thanks for your time.
