It may be a niche market. However there are 6 record stores in the Orlando area that sell new vinyl and they are packed with 20 somethings and foreign tourist's all the time.Even at the local Malls that have a FYE Store or Barnes & Noble Book store have a Vinyl section now.
I guess it helps to have 3 large Colleges in the area. And even the used vinyl stores in the area get a lot of business.
