Hi, I have to get my 14 year a new trombone as he is currently rehearsing for grade 5. His current one has been called 'beyond economical repair'. So he is buying this one as he has wrecked the last two we have bought him. He is adamant he doesn't want to quit. Obviously we will help him out if its more money. Every time we have to buy a new one I just don't know what to get for him. Any help appreciated! Thanks
