I love neon signs and love that Texans helmet one.
Not a fan of Coors Light but that is cool. I would be tempted to offer you something if my wife didn't hate neon signs so much.
Have you tried ebay or Craigslist? Neon signs aren't cheap and I would think you could at least get $300 for that thing.
Oh, post that here also http://www.texanstalk.com/forums/showthread.php?t=95661
There are some members here working on some real nice Texans man caves. Maybe one of them would be interested.
