Howdy folks, I'm not sure if this is the correct spot for this question so if it's not...SORRY!! Anyway, does anyone have any suggestions on a good way to get a "proper" appraisal for your trumpet(s)? This is strictly for insurance purposes so the more accurate the better. I know that I could look them up & get the current retail price, but those "pesky" insurance people want something in writing. So, thanks for your help!
