I purchased a custom home theater marquee from a company called HollywoodMarquees. You tell them what custom artwork you want on your marquee and they design it for you, including audio format logos like DTS Master Audio, formats you support in your theater like Blu-ray or 3D, etc.
They also have letter-trak lines you can have added so you can put in your own custom titles. See below for an example of my Freddy vs Jason title.
They have a variety of sizes and options available. The construction quality is top notch, being made mostly of aluminum with a plexiglass front. The blinking / rotating LED lights are also a nice looking option. You can check them out on their website and they also have an ebay store.
Check out the video of my unboxing and installation below.
