I’m looking for an LED Moving Message sign (scrolling marquee) that is programmable through RS-232.
I’d like it to be more than 3 inches tall. The bigger the better. Brand new, the cheapest I can find is $120 (ssl30.chi.us.securedata.net/litexpo.com/merchantmanager/product_info.php?cPath=1&products_id=1).
Thanks
