Brian Bowers has many auto harps- he had really good, insulated bags. you may want to make sure the one you get has padding/insulation layer so that it will be protected from temperature extremes-this will help it stay in tune...i have seen this company booth at some fairs: blue heron here is a link...

I have a case called climate case for my guitar. it has a silver cover which reflects light and heat, i do not htink they make them anymore- might have sold the biz to a guitar company. i think they used to be made by allen guitars (?) in grass valley or nevada city california.
