I think bows can be a personal choice. Not to mention the fact that there are so many bows out there that it’s nigh impossible for one person to try them all. Also, there are very expensive bows out there that may be spectacular, but due to their value, are not suitable for every violinist.
I will say a few things, however.
1. There is a reason that student bows are called student bows! They are cheap (~$20), because many beginners/beginner’s parents are already considering the adventure to be enough of an expense what with the cost of the violin and lessons. Also, students are only learning how to use rosin and that they need to loosen and tighten the bow. It would certainly be a pity to see a nice bow get misused just because its owner was not yet taught how to care for it.
2. Two of the factors you should consider when buying a bow is the weight and the balance of that weight. These factors are what will affect how well you are able to maneuver the bow and play each string.
3. Test out the loosening and the tightening of the bow. I once had a bow that had a mis-correlation between the screw and the hairs. The result was that the screw came out when I loosened the bow, and one day I couldn’t get it back in (the day of a concert, actually!!).
