Hi. I`m looking for a 16" used viola for my daughter. (she`s totally outgrown her first student 13" which I will be selling or trading in) Would like higher quality so I don`t have to trade up again for at least 2-3 years, so looking used to get a bargain on a better quality instrument. Will buy case and bow separately, looking to spend about $400 on the viola itself. Rich, soft, deep sound with one piece back desired. Will restring with our own. Any suggestions what would work well for her or how I can use the internet to find a good quality, bargain on a viola like this? Thanks.
