I am looking at purchasing a Double bass. I work for a large music store chain and could purchase a Holbein or a Carlo Robelli very inexpensively, although don't know if it would be worth it. I have been looking at an Antonius bass with no model number or other identifying marks for $700 w/ case. I don't know a whole lot on what I'm looking for so any info would be great! Thanks in advance for the feedback.
